fix(es/react-compiler): Grow the stack while converting expressions `convert_expr` and `convert_expression` recurse once per member-call link, so a long chain overflows a 2 MiB thread stack. Wrap both in `stacker::maybe_grow`, behind a default `stacker` feature, matching `swc_ecma_parser`. Refs #12423 Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

fix(es/react-compiler): Skip programs that `fast_check` rules out In `infer` and `annotation` modes the React Compiler only compiles functions that `fast_check::is_required` can see. Return early from `transform` when it reports `false`, so files without React code skip AST conversion and HIR lowering. `all` and `syntax` stay ungated.

fix(html/minifier): Preserve adjacent script elements (#12411) **Description:** Keep adjacent HTML and SVG `<script>` elements separate during minification. Merging them changed evaluation boundaries, `document.currentScript`, and CSP hashes; a throw in the first script could also cause the second script to be dropped. Compatible `<style>` elements continue to merge. Add regression fixtures for throwing scripts, `minifyJs: false`, `document.currentScript`, and module and SVG scripts. Update the existing script fixtures. Verified with `cargo test -p swc_html_minifier`, `cargo fmt --all`, and `cargo clippy --all --all-targets -- -D warnings`. **BREAKING CHANGE:** `mergeMetadataElements` no longer merges `<script>` elements. Minified HTML now retains their separate element boundaries. **Related issue (if exists):** Closes #12402

fix(es/parser): Parse optional renamed Flow component parameters (#12410) **Description:** Parse optional renamed Flow component parameters such as `foo as bar?: T` and `'data-testid' as dataTestId?: T`. Mark the renamed binding as optional while preserving the existing behavior for optional parameters and required renamed parameters. Add Flow parser fixtures for identifier and string keys, a default value, and a duplicate optional marker error. Include a patch changeset for `swc_ecma_parser` and `swc_core`. **Tests:** - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` - `cargo test -p swc_ecma_parser --features flow -- --quiet --skip errors_tests__typescript_errors__type_only_import_specifier__invalid_type_only__input_ts` - `cargo test -p swc_ecma_transforms_typescript --test flow_strip_correctness issue_12405 -- --quiet` The unfiltered parser suite has one unrelated pre-existing failure in `invalid_type_only/input.ts`; it also fails without the Flow feature enabled. **BREAKING CHANGE:** None. **Related issue (if exists):** Fixes #12405

fix(html/parser): preserve customizable select markup (#12413) **Description:** Preserve customizable select markup and rich option content during HTML parsing and minification. Previously, the parser reported `<button>`, `<selectedcontent>`, and phrasing elements inside `<option>` as stray tags and dropped them. - Process general select content with the in-body rules while retaining select-specific handling for options, optgroups, input, and table contexts. - Add parser, fragment, and minifier regression fixtures. Keep modern expectations for affected pinned html5lib cases in local overrides. - Add the required Rust changeset. Validation: `cargo test -p swc_html_parser`, `cargo test -p swc_html_minifier`, `cargo fmt --all`, and `cargo clippy --all --all-targets -- -D warnings` all passed locally. **Related issue (if exists):** Closes #12403
