0d0bb17ad9 feat(transformer): complete the async-to-generator plugin (#6658) 
In this PR, most of the async functions have transformed correctly. But the async arrow functions don't fully transform correctly yet, it is related to we need to transform the arrow function to the generator function. For example:

Input:
```js
function declaration() {
  const asy = async () => {
  console.log(this.name)
 }
}
```

Output:
```js
function declaration() {
  const asy = babelHelpers.asyncToGenerator(function* () {
     console.log(this.name);
  });
}
```

Expected Output:

```js
function declaration() {
  var _this = this;
  const asy = /*#__PURE__*/function () {
    var _ref = babelHelpers.asyncToGenerator(function* () {
      console.log(_this.name);
    });
    return function asy() {
      return _ref.apply(this, arguments);
    };
  }();
}
```

From the expected output, we haven't handled `this` correctly, which means even if the `arrow-function` plugin doesn't enable, we still need to handle this correctly as the `arrow-function` plugin does, and further question if `arrow-function` plugin is enabled, how to avoid these making conflict?

I thought we may move out the implementation of `arrow-function` and as a common helper, this way every plugin can handle this well

90c786c420 feat(regular_expression)!: Support ES2025 Duplicated named capture groups (#6847) 
Closes #6358

@preyneyv I know you've been working on this problem.

This is an implementation that has been dormant on my local for a while.

- All tests are passing
- However, the approach is simple but not general, so there might be some edge cases that were missed
- There's also room for improvement in terms of performance

For these reasons, it was marked as WIP for me.

I believe the test cases and other parts are usable, so feel free to fork and replace them with your implementation if you'd like.

chore(tasks/lint_rules): sync rules with ESLint v9 (#6777) 
The previous version of the `react-perf` ESLint plugin was holding us
back from updating this to ESLint V9. I've manually specified the ESLint
version here, because we want to make sure we are running the latest
major version of ESLint which changes a lot of things.

Also changed it so that rules which are not supported and also
implemented do not get counted twice in the total count. For example,
`eslint/no-with` is marked as not supported but it is still implemented.
This was previously counted for both, which made it look like we had an
additional rule implemented.

e8f8409d01 fix(ast_tools): fix miscalculation of enum layouts. (#5774) 
Fixes a bug with how we were calculating the size of enums when there are different padding on variants and there aren't enough niches. Now it aligns the largest variant size to the largest alignment before consuming niches.

41a6ad63b6 refactor(ast_tools): add Derive::snake_name method (#6717) 
Follow-on after #6404. Add `Derive::snake_name` method which defaults to `Self::trait_name().to_case(Case::Snake)`, but can be overridden. This allows moving the "special case" code for `ESTree` filename into `estree.rs`.

This is tracking issue for `eslint-plugin-vitest`.


There are 51(+ 1 deprecated) rules.

- 1/8 recommended rules are remaining as TODO
- 30/43 not recommended rules are remaining as TODO


To get started, run the following command:

```sh
just new-vitest-rule <RULE_NAME>
```

Then register the rule in `crates/oxc_linter/src/rules.rs` and also
`declare_all_lint_rules` at the bottom.

53049fe7fa fix(wasm): remove type defs for ArrayExpressionElement and Elision (#6683) 
Follow-on after #6404.

`ArrayExpressionElement` and `Elision` are not used in the TS types, because `ArrayExpression` has an override for the field it uses.

002289b4b1/crates/oxc_ast/src/ast/js.rs (L293-L302)

Prevent these TS type defs being emitted by introducing a new `#[estree(custom_ts_def)]` attr, to go with `#[estree(custom_serialize)]`.

## What This PR Does

1. Recover on, and provide a better message for, invalid `export` modifier on constructor parameters. Before, an `unexpected token` error would be produced and the parser would panic. Now, the parser recovers and produces a message saying `'export' modifier cannot appear on a parameter.`
  ```ts
class Foo {
    constructor(export x: number) {}
}
  ```

2. Recover on, and provide a better message for, invalid modifiers on index signatures. Same recovery/message characteristics as above.
  ```ts
class Foo {
    public [x: string]: string;
}
```

80266d85c9 feat(linter)!: support plugins in oxlint config files (#6088) 
> Closes #5046
This PR migrates the linter crate and oxlint app to use the new `LinterBuilder` API. This PR has the following effects:

1. `plugins` in oxlint config files are now supported
2. irons out weirdness when using CLI args and config files together. CLI args are now always applied on top of config file settings, overriding them.

# Breaking Changes
Before, config files would override rules set in CLI arguments. For example, running this command:
```sh
oxlint -A correctness -c oxlintrc.json
```
With this config file
```jsonc
// oxlintrc.json
{
  "rules": {
    "no-const-assign": "error"
  }
}
```
Would result in a single rule, `no-const-assign` being turned on at an error level with all other rules disabled (i.e. set to "allow").

Now, **CLI arguments will override config files**. That same command with the same config file will result with **all rules being disabled**.

## Details

For a more in-depth explanation, assume we are running the below command using the `oxlintrc.json` file above:
```sh
oxlint -A all -W correctness -A all -W suspicious -c oxlintrc.json
```

### Before
> Note: GitHub doesn't seem to like deeply nested lists. Apologies for the formatting.

Here was the config resolution process _before_ this PR:
<details><summary>Before Steps</summary>

1. Start with a default set of filters (["correctness", "warn"]) if no filters were passed to the CLI. Since some were, the filter list starts out empty.
2. Apply each filter taken from the CLI from left to right. When a filter allows a rule or category, it clears the configured set of rules. So applying those filters looks like this
  a. start with an empty list `[]`
  b. `("all", "allow")` -> `[]`
  c. `("correctness", "warn")` -> `[ <correctness rules> ]`
  d. `("all", "allow")` -> `[]`
  e. `("suspicious", "warn")` -> `[ <suspicious rules> ]`. This is the final rule set for this step
3. Apply overrides from `oxlintrc.json`. This is where things get a little funky, as mentioned in point 2 of what this PR does. At this point, all rules in the rules list are only from the CLI.
  a. If a rule is only set in the CLI and is not present in the config file, there's no effect
  b. If a rule is in the config file but not the CLI, it gets inserted into the list.
  c. If a rule is already in the list and in the config file
    i. If the rule is only present once (e.g. `"no-loss-of-precision": "error"`), unconditionally override whatever was in the CLI with what was set in the config file
    ii. If the rule is present twice (e.g. `"no-loss-of-precision": "off", "@typescript-eslint/no-loss-of-precision": "error"`),
      a. if all rules in the config file are set to `allow`, then turn the rule off
      b. If one of them is `warn` or `deny`, then update the currently-set rule's config object, but _leave its severity alone_.

  So, for our example, the final rule set would be `[<all suspicious rules: "warn">, no-const-assign: "error"]`

</details>

### After
Rule filters were completely re-worked in a previous PR. Now, lint filters aren't kept on hand-only the rule list is.

<details><summary>After Steps</summary>

1. Start with the default rule set, which is all correctness rules for all enabled plugins (`[<all correctness rules: "warn">]`)
2. Apply configuration from `oxlintrc.json` _first_.
  a. If the rule is warn/deny exists in the list already, update its severity and config object. If it's not in the list, add it.
  b. If the rule is set to allow, remove it from the list.

  The list is now `[<all correctness rules except no-const-assign: "warn">, no-const-assign: "error"]`.

3. Apply each filter taken from the CLI from left to right. This works the same way as before. So, after they're applied, the list is now `[<suspicous rules: "warn">]`

ccb7bdcc56 fix(transformer): exponentiation transform: do not replace object when private property (#6313) 
Fix exponentiation operator transform to bail out early if a private class property.

We can't transform this:

```js
class C {
    #p;
    method() {
        this.#p **= 2;
    }
}
```

But we should at least leave it alone. Previously `get_obj_ref` called `ast.move_expression(expr)` on the member expression's object before bailing out, so example above was transformed to:

```js
class C {
    #p;
    method() {
        null.#p **= 2; // <-- `null`
    }
}
```

This PR makes it spot this case early and bail out *before* calling `ast.move_expression(expr)`.

5a73a663dc refactor(regular_expression)!: Simplify public APIs (#6262) 
This PR makes 2 changes to improve the existing API that are not very useful.

- Remove `(Literal)Parser` and `FlagsParser` and their ASTs
- Add `with_flags(flags_text)` helper to `ParserOptions`

Here are the details.

> Remove `(Literal)Parser` and `FlagsParser` and their ASTs

Previously, the `oxc_regular_expression` crate exposed 3 parsers.

- `(Literal)Parser`: assumes `/pattern/flags` format
- `PatternParser`: assumes `pattern` part only
- `FlagsParser`: assumes `flags` part only

However, it turns out that in actual usecases, only the `PatternParser` is actually sufficient, as the pattern and flags are validated and sliced in advance on the `oxc_parser` side.

The current usecase for `(Literal)Parser` is mostly for internal testing.

There were also some misuses of `(Literal)Parser` that restore `format!("/{pattern}/{flags}")` back and use `(Literal)Parser`.

Therefore, only `PatternParser` is now published, and unnecessary ASTs have been removed.
(This also obsoletes #5592 .)

> Added `with_flags(flags_text)` helper to `ParserOptions`

Strictly speaking, there was a subtle difference between the "flag" strings that users were aware of and the "mode" recognised by the parser.

Therefore, it was a common mistake to forget to enable `unicode_mode` when using the `v` flag.

With this helper, crate users no longer need to distinguish between flags and modes.

900cb46f6c refactor(transformer): convert ModuleImports into common transform (#6186) 
An alternative version of #6177.

Convert `ModuleImports` into a common transform. Works much as before, but it inserts `import` / `require` statements by passing them to `TopLevelStatements` common transform, so they get inserted in one go with any other inserted top-level statements. This avoids shuffling up the `Vec<Statement>` multiple times, which can be slow with large files.

`VarDeclarations` also inserts any declarations via `TopLevelStatements` but runs after `ModuleImports`, so can control whether a `var` statement is inserted before or after `import` statements by inserting it via `VarDeclarations` (to appear after `import` statements) or directly into `TopLevelStatements` (to appear before `import` statements). Insertion order is not actually important, but allows us to match Babel's output and pass its tests.

First step towards #5049.

Various transforms need to add a `var` statement at top of enclosing statement block.

```js
// Input
a ??= b;
```

```js
// Output
var _a;
(_a = a) !== null && _a !== void 0 ? _a : (a = b);
```

Each of these transforms previously maintained it's own stack and added `var` statements individually.

Share this functionality in a "common" utility transform which maintains a single stack to serve them all.

b240b42eb9 fix(rulegen): handle raw string literals correctly (#5991) 
Currently, we are not handling raw string literals correctly and just translating them as normal Rust string literals, which causes compile errors and also misses some cases. This PR updates it so that we detect usage of `String.raw` and translate it as a Rust raw string literal.

d24985ed51 feat(linter): add oxc-security/api-keys (#5906) 
## What This PR does
Adds a new `oxc-security/api-key` rule that scans for hard-coded API keys.

It is broken up into "secret rules", where each one is responsible for finding a different kind of key. It is architecturally identical to how lint rules themselves. This PR also includes the first of these rules, for AWS access key IDs.

Logic and rules are based on [keyhunter](https://github.com/Donisaac/keyhunter). I've licensed that repo under GNU GPLv3, but it's my code and I can do what I want with it 😈 (read: I'm fine with it being MIT for oxc).

This PR is a complete feature in its own right, but does not represent the end of this work. See https://github.com/oxc-project/backlog/issues/116 to track overall progress.
