fix(es/codegen): preserve TypeScript token boundaries Keep type argument closers and assertion openers distinct from adjacent operators. Separate nested type openers and retain semicolons before type assertions and JSX. Preserve empty generic constructor arguments. Batch empty argument lists and inline type argument emission. Add TS/TSX fixtures with compact output, AST, and source-map checks.

perf(hstr): allow Atom::as_str to inline across crates (#12522) **Description:** `Atom`'s `Deref` and `AsRef<str>` implementations are inline, but both call `Atom::as_str` without an inline hint. Add `#[inline]` to make that implementation available for cross-crate inlining. Add patch changesets for `hstr` and `swc_core`. An isolated CodSpeed benchmark confirmed that the separate `Atom::as_str` call disappears. The [CPU simulation](https://app.codspeed.io/swc-project/swc/runs/compare/6acd782a4b60f59a90e4f4e9..6acd78494b60f59a90e4f4f0) measured a 2.4% regression for 7-byte strings and no change for 20-byte strings. The [macOS walltime run](https://app.codspeed.io/swc-project/swc/runs/compare/6acd774e4b60f59a90e4f4c1..6acd777f4b60f59a90e4f4c8) measured lower best times for both cases. These results do not establish a consistent speedup or an end-to-end performance change. Validation: - `cargo test -p hstr` (60 unit tests and 1 doc test passed) - `cargo fmt --all` (passed) - `cargo clippy --all --all-targets -- -D warnings` (passed) **BREAKING CHANGE:** None. **Related issue (if exists):** Closes #12516
