0ca10e270a refactor(transformer): use ctx.var_declarations.create_var* methods (#7666) 
It turns out these APIs are very useful, we remove many boilerplate code.

8a788b8f4b feat(parser)!: Build ModuleRecord directly in parser (#7546) 
This has the benefit of:

* expose dynamic import / import meta info from parser
* 1 less ast shallow in semantic builder
* no ast walk in oxc's module lexer
* some more benefits coming soon

4d6bd07afe fix(transformer/async-generator-functions): correct all binding scope id (#7425) 
Fixed a bunch of semantic errors by removing moving binding logic 😢. This plugin constructs a complex `for-await` replacement so that I wrongly move to an incorrect scope.

27b2268a6c refactor(semantic)!: remove SymbolFlags::Export (#7414) 
close: #7338
close: #7344

The `SymbolFlags::Export` is Initially used to solve `ExportSpecifier` that is not `IdentifierReference` that causes we cannot determine whether a Binding is not used everywhere by `Semantic`.

Since #3820 this problem is solved, so we don't need `SymbolFlags::Export` no longer. Also, removing this can help us easier to pass the `Semantic` check in `Transformer`

6f0fe38bff fix(semantic)!: correct all ReferenceFlags::Write according to the spec (#7388) 
close #7323

According to the specification re-design the JavaScript-part ReferenceFlags inferring approach.

* ... See references of https://tc39.es/ecma262/#sec-putvalue

### Changes

1. The left-hand of `AssignmentExpression` is always `ReferenceFlags::Write`
```js
let a = 0;
console.log(a = 0);
            ^ Write only
```

2. The `argument` of `UpdateExpression` is always `ReferenceFlags::Read | Write`
```js
let a = 0;
a++;
^ Read and Write
```

This change might cause some trouble for `Minfier` to remove this code, because ‘a’ is not used elsewhere. I have taken a look at `esbuild` and `Terser`. Only the `Terser` can remove this code.

ede10dc030 fix(transformer/async-to-generator): incorrect transform when super expression is inside async method (#7171) 
After transformation, super expressions have moved to unexpected places. This PR replaces super expression to call expression, and then inserts the super methods to the top of the method body.

For example:

Before:
```js
class G {
  async method() {
    super.foo()
  }
}
```

After:
```js
class G {
  method() {
    var _superprop_getFoo = () => super.foo,
      _this = this;
    return _asyncToGenerator(function* () {
      _superprop_getFoo().call(_this);
    })();
  }
}```

Support for inferring function name from ObjectPropertyValue's key

fix(ast): Fix StaticMemberExpression.get_first_object (#6969) 
I think `get_first_object` does not return expected expression.

For example, in case of `foo.bar.a`, it doesn't return `foo` but
`foo.bar`.

**Expected**
```
{
  "type": "Identifier",
  "start": 0,
  "end": 3,
  "name": "foo"
}
```

**Actual**
```
{
   "type":"StaticMemberExpression",
   "start":0,
   "end":7,
   "object":{
      "type":"Identifier",
      "start":0,
      "end":3,
      "name":"foo"
   },
   "property":{
      "type":"Identifier",
      "start":4,
      "end":7,
      "name":"bar"
   },
   "optional":false
}
```

4dc5e51cb1 fix(transformer): only run typescript plugin for typescript source (#6889) 
closes #6865

TypeScript plugin changes import / export statements so it needs to be turned off for non-typescript files. This should also give a little performance boost for non-typescript files.

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.
