fix(es/minifier): Drop unused callbacks passed to empty functions Reduce known empty identifier calls in non-final sequence positions when arguments are function expressions, arrow functions, or literals without spreads. Preserve reference semantics and require reduce_vars and side_effects. Add focused snapshot and execution coverage, including the exact top-level reproduction that reduces to console.log(42).

ci: Allow LingyuCoder in the Rspack group (#12685) **Description:** Add `LingyuCoder` to the `rspack` group in the approved contributor list. LingyuCoder is on the Rspack team and is the author of #12684. The contributor policy accepts pull requests only from bots, repository writers, and listed contributors. A change to the list takes effect only after it is merged into `main`. For this reason, this change is separate from #12684. **Related issue (if exists):** Related pull request: #12684 **Validation:** - `npm test` in `.github/actions/contributor-policy`: 89 passed at `743a60e8b3`. - `cargo fmt --all`: passed at `743a60e8b3`. - `cargo clippy --all --all-targets -- -D warnings`: passed at `743a60e8b3`. Cargo emitted profile and MSRV configuration warnings. - No changeset is required because no Rust crates changed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Sonnet 5.5 <noreply@anthropic.com>

fix(sourcemap): Preserve sources without embedded content when flattening (#12680) **Description:** Preserve every source when lazily flattening indexed sourcemaps with missing or short `sourcesContent` arrays. Zipping the two arrays previously dropped sources and cleared their token mappings. Add regression coverage for optional source content, nested sections, offsets, names, and ignore lists. **Validation:** - `cargo test -p swc_sourcemap --locked` - `cargo fmt --all -- --check` - `cargo clippy --all --all-targets --locked -- -D warnings`
