refactor(diagnostics)!: return a Diagnostics type instead of Vec<OxcDiagnostic> ( #23217 )
...
## Summary
Introduces `oxc_diagnostics::Diagnostics` — a `Vec<OxcDiagnostic>` newtype that knows the difference between errors and warnings — and makes it the standard diagnostics return value across oxc.
- **New type**: `Diagnostics` with `has_errors()`, `has_warnings()`, `errors()`, `warnings()`, plus `Vec`-like ergonomics (Deref, `IntoIterator`, `Extend`, `From`/`Into<Vec>`) so most call sites are unchanged.
- **Return types**: `ParserReturn`, `SemanticBuilderReturn`, `IsolatedDeclarationsReturn`, the React Compiler `TransformResult`/`LintResult`, and `TransformerReturn` now expose `diagnostics: Diagnostics` instead of `errors: Vec<OxcDiagnostic>` (the React Compiler's separate `errors`/`warnings` are merged into one severity-tagged list).
- **Behaviour**: a React Compiler **error** now stops the transform (no output), while **warnings** flow through and the transform continues. `compile()` aborts codegen only when `diagnostics.has_errors()` — warnings alone no longer abort (previously any diagnostic did).
## Breaking change
Consumers reading `*.errors` on these return values must read `*.diagnostics`. React Compiler consumers that read `.errors`/`.warnings` separately should use `diagnostics.has_errors()` / `diagnostics.errors()` / `diagnostics.warnings()`.
Parser/semantic/isolated-declarations fatality is otherwise unchanged. Builds on the React Compiler transform feature (#23201 ).

feat(codegen)!: introduce CommentOptions ( #12114 )
...
Control printing of comments more precisely via more options:
The logic change here is that jsdoc is no longer part of annotation
comments.
```rust
pub struct CommentOptions {
/// Print normal comments that do not have special meanings.
///
/// At present only statement level comments are printed.
///
/// Default is `true`.
pub normal: bool,
/// Print jsdoc comments.
///
/// * jsdoc: `/** jsdoc */`
///
/// Default is `true`.
pub jsdoc: bool,
/// Print annotation comments.
///
/// * pure: `/* #__PURE__ */` and `/* #__NO_SIDE_EFFECTS__ */`
/// * webpack: `/* webpackChunkName */`
/// * vite: `/* @vite-ignore */`
/// * coverage: `v8 ignore`, `c8 ignore`, `node:coverage`, `istanbul ignore`
///
/// Default is `true`.
pub annotation: bool,
/// Print legal comments.
///
/// * starts with `//!` or `/*!`.
/// * contains `/* @license */` or `/* @preserve */`
///
/// Default is [LegalComment::Inline].
pub legal: LegalComment,
}

<a id="1.85.0-Compatibility-Notes"></a>
## Compatibility Notes
- [`rustc` no longer treats the `test` cfg as a well known check-cfg](https://redirect.github.com/rust-lang/rust/pull/131729 ), instead it is up to the build systems and users of `--check-cfg`\[^check-cfg] to set it as a well known cfg using `--check-cfg=cfg(test)`.
This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests.
[Cargo (for now) unconditionally sets the `test` cfg as a well known cfg](https://redirect.github.com/rust-lang/cargo/pull/14963 ).
\[^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html
- [Disable potentially incorrect type inference if there are trivial and non-trivial where-clauses](https://redirect.github.com/rust-lang/rust/pull/132325 )
- `std::env::home_dir()` has been deprecated for years, because it can give surprising results in some Windows configurations if the `HOME` environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function.
- [Make `core::ffi::c_char` signedness more closely match that of the platform-default `char`](https://redirect.github.com/rust-lang/rust/pull/132975 )
This changed `c_char` from an `i8` to `u8` or vice versa on many Tier 2 and 3
targets (mostly Arm and RISC-V embedded targets). The new definition may
result in compilation failures but fixes compatibility issues with C.
The `libc` crate matches this change as of its 0.2.169 release.
- [When compiling a nested `macro_rules` macro from an external crate, the content of the inner `macro_rules` is now built with the edition of the external crate, not the local crate.](https://redirect.github.com/rust-lang/rust/pull/133274 )
- [Increase `sparcv9-sun-solaris` and `x86_64-pc-solaris` Solaris baseline to 11.4.](https://redirect.github.com/rust-lang/rust/pull/133293 )
- [Show `abi_unsupported_vector_types` lint in future breakage reports](https://redirect.github.com/rust-lang/rust/pull/133374 )
- [Error if multiple super-trait instantiations of `dyn Trait` need associated types to be specified but only one is provided](https://redirect.github.com/rust-lang/rust/pull/133392 )
- [Change `powerpc64-ibm-aix` default `codemodel` to large](https://redirect.github.com/rust-lang/rust/pull/133811 )
<a id="1.85.0-Internal-Changes"></a>
## Internal Changes
These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.

style(all): replace #[allow] with #[expect] ( #8930 )
...
Replace `#[allow]` with `#[expect]` through the whole codebase.
This also surfaced many places where the `#[allow]` attributes were outdated/pointless and could be removed entirely.
Only places `#[allow]` remains are:
1. In generated code and macros, where lint errors may or may not be triggered depending on the generated code.
2. A few places where clippy malfunctions. These use e.g. `#[allow(unused, clippy::allow_attributes)]`.

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);
```
