be4642fc02 feat(semantic): transform checker check child scope IDs (#5410) 
Transform checker check child scope IDs. If we have to track child scope IDs, we should make sure they're correct!

af5713e411 refactor(semantic): transform checker continue checks if missing IDs (#5259) 
Transform checker don't bail out if some IDs missing from AST. Continue to check for other problems.

Also simplify iterating over pairs of IDs.

ee7ac8b0b7 refactor(semantic): store all data in PostTransformChecker in transform checker (#5050) 
Pure refactor of transform checker. Store all scope data in `PostTransformChecker` so it doesn't need to be passed around. `SemanticData` contains a full set of all semantic data for semantic pass, so we have 2 instances of it for 1. after transform and 2. rebuilt semantic.

c220730779 feat(coverage): check symbols and scopes after transformation (#4917) 
closes https://github.com/oxc-project/oxc/issues/4790

@overlookmotel enjoy ... take a look at the snapshots and probably nothing else.

The snapshots are minimal right now, but it's already showing symbols from import specifiers are not being removed. We can iterate on the snapshot representation to aid debugging later.

I'll extend this to `transformer_conformance` and `oxc-monitor` in an up coming PR.

e78cba6464 refactor(minifier): ast passes infrastructure (#4625) 
After studying google closure compiler, I'm leaning towards a multi-ast-pass infrastructure for the minifier.

This is one of the few places where we are going to trade maintainability over performance, given the goal of the minifier is compression size not performance.

All of the terminologies and separation of concerns are aligned with google closure compiler.

Infrastructure of `terser` and `esbuild` are not suitable for us to study nor pursuit. Their code are so tightly coupled - I failed to comprehend any of them every time I try to walk through a piece of optmization. Google closure compiler despite being written in Java, it's actually the most readable minifier out there.

To improve performance between ast passes, I envision a change detection system over a portion of the code.

The benchmark will demonstrate the performance regression of running 5 ast passes instead of 2.

To complete this PR, I need to figure out "fix-point" and order of these ast passes.

5c38a0fd69 feat(codegen)!: new code gen API (#3740) 
This PR introduces two type alias to avoid the confusing const generic `pub struct Codegen<'a, const MINIFY: bool>`

* CodeGenerator - Code generator without whitespace removal.
* WhitespaceRemover - Code generator with whitespace removal.

Usage is changed to a builder pattern:

```rust
CodeGenerator::new()
  .enable_comment(...)
  .enable_sourcemap(...)
  .build(&program);
```
