fix: Correct quoted package name in changeset (#12387) **Description:** The release workflow fails in `cargo bump` because the changeset parser treats the quoted package key as part of the package name (`"swc_estree_compat"`). Remove the quotes so the package matches Cargo metadata and crate publishing can proceed. **BREAKING CHANGE:** None. **Related issue (if exists):** N/A

fix(es/minifier): preserve destructuring patterns with PURE-annotated initializers A `/*#__PURE__*/` annotation on the initializer of a destructuring declaration only describes the evaluation of the initializer itself. The pattern still performs property reads, which can invoke getters, and checks the initializer value for nullishness, which can throw, so the annotation never licensed removing the pattern. `take_pat_if_unused` treated an annotated initializer (call, `new` or tagged template) as if the pattern itself were annotated, which dropped unused declarations like `const { a } = /*#__PURE__*/ x()` and could eliminate getter accesses with side effects. Only an annotation written directly on the pattern (the side table added for object and array patterns) or `pure_getters` now allows dropping a pattern. Unused plain bindings such as `const a = /*#__PURE__*/ x()` are still removed. The expected output of `tests/fixture/issues/9459` is updated because it asserted the old behavior for array patterns; per-site pattern annotations remain the way to opt into dropping them. Fixes #12373

fix(es/parser): recognize named optional and rest tuple elements (#12368) **Description:** Accept TypeScript tuples with unnamed optional elements followed by named optional or rest elements, such as `[number?, value?: string]` and `[number?, ...rest: string[]]`. Previously, named optional and rest elements were mistaken for required elements and rejected.
