## Summary

- Bump oxc Rust crates and `@oxc-project/*` / `oxc-*` npm packages from `0.132.0` to `0.133.0`. ~~Bump `oxc_resolver` / `oxc_resolver_napi` from `11.19.1` to `11.19.2`.~~
- Regenerate `embedded_helpers.rs` to point at `@[email protected]` (version string only — no helper-content drift).
- Handle two new oxc fields surfaced by `cargo check`:
  - `oxc::transformer::DecoratorOptions.strict_null_checks` — hardcoded to `true` in the `From` impl (matches oxc's default). Exposing it through rolldown's wrapper would be a separate API change.
  - `oxc_minify_napi::CodegenOptions.legal_comments` — set to `None`.
- Extend `DecoratorOptionSchema` and `CodegenOptionsSchema` in `validator.ts` to mirror the new optional fields.
- Refresh 32 snapshots driven by upstream oxc PR [#22547](oxc-project/oxc#22547) ("fix(minifier): preserve IIFE structure in DCE-only mode"). In DCE-only mode (rolldown's per-module preprocess via `Compressor::dead_code_elimination_with_scoping`), oxc no longer inlines `(() => …)()` IIFEs that carry — or could carry — `/*#__PURE__*/` annotations, so downstream tree-shaking can see them. Empty-IIFE elision still fires. Side effects: `property_read_side_effects` now correctly tree-shakes `/*#__PURE__*/ test().a.b.c;` lines and drops the previously spurious `INVALID_ANNOTATION` warnings; TS class `(() => new Foo())()` patterns and `Symbol((() => Math.random() < 0.5)() ? …)` calls are preserved as the sources actually wrote them; `dce_of_iife/diff.md` divergence vs esbuild shrunk.

## Issues fixed

Pulled in from upstream oxc fixes between 0.132.0 and 0.133.0:

- Fixes #9437 — Pure-annotated IIFE returning an array is inlined (via oxc [#22547](oxc-project/oxc#22547))
- Fixes #9494 — Cross-module enum inlining mis-folds auto-increment member to 0 (via oxc [#22646](oxc-project/oxc#22646))
- Fixes #9408 — Rolldown drops `@preserve` from `/* #__PURE__ -- @preserve */` comments (via oxc [#22525](oxc-project/oxc#22525) "preserve verbatim text of pure/no-side-effects comments")
- Partially addresses #8688 — `dce/dce_of_iife` esbuild divergence shrunk (via oxc [#22589](oxc-project/oxc#22589) "drop empty-body IIFE wrapper when called with arguments")

Also relevant: oxc [#22566](oxc-project/oxc#22566) reduces false-positive `PureNotApplied` warnings (the warnings system landed in rolldown #9381) by applying PURE through member-access chains.

## Test plan

- [x] `cargo check --workspace --all-targets`
- [x] `just update-generated-code`
- [x] `just test-update`
- [x] `just ued`
- [x] `just roll` — 32 Rust suites pass (0 failed), 1212 node tests pass (0 failed), TS lint+types clean on 804 files
