refactor(es/react-compiler): Preserve TS metadata during AST roundtrip (#11950) **Description:** This PR improves TypeScript metadata preservation in the React Compiler AST roundtrip. React Compiler's AST does not losslessly represent several SWC TypeScript fields, so reverse conversion now restores those fields from explicitly preserves SWC shells first and uses RawNode parsing only as a cold fallback. Main changes: - Preserve typed catch clause parameters during forward conversion and restore them in reverse conversion. - Replace separate JSX opening/new/tagged type-argument shells with a shared `TsOptionalInstantiation`. - Split TS instantiation metadata out of `TsExprShell`, and simplify `TsExprShell` to wrapper span plus type annotation. - Remove the generic `load_ts_expr_for_span` post-pass; TS expression wrappers now restore their own preserved metadata in their concrete branches. - Convert pattern-like nodes without type annotations on the hot path, then fill top-level TS metadata from preserved AST or cold RawNode fallback. - Improve `TSDeclareFunction` fallback params by recovering raw identifier/rest names, optional flags, and top-level type annotations instead of placeholder params. - Restore preserved TS module-like items directly instead of rebuilding module ids from RawNode JSON.

fix(es/es2022): Correct scope for private property brand checks (#11953) **Description:** This PR fixes a bug where `WeakSet` instances generated for `#field in object` brand checks were accidentally scoped to the closest following block statement (often a sibling class constructor) rather than the parent module scope. The bug was caused by a state leakage in `PrivatePropertyInObjectPass`. AST traversal would accumulate `self.vars` across classes and unconditionally dump them into the very next `exit_stmts` hook it encountered. I resolved this by introducing a `vars_stack` to the pass, pushing a fresh scope upon entering a block/module, and popping it on exit. This ensures injected variables strictly stay within the AST scope they were generated in. **Testing:** I have added a test fixture containing the exact reproduction code and configuration from #11931. The baseline output correctly places the `var _brand_check_x = new WeakSet();` outside of the child class scope. **Related issue:** - Closes #11931

fix(react-compiler): avoid reporting non-fatal success errors as diagnostics (#11951) ## Summary Avoid converting error-level React Compiler logger events from `CompileResult::Success` into SWC diagnostics. React Compiler can preserve `CompileError` logger events while still returning `CompileResult::Success`, for example when `panicThreshold` is `none`. Those events should remain available on the transform result, but should not become SWC diagnostics that fail compilation. Warning and hint events from successful results are still surfaced as SWC warnings. Fatal results (`CompileResult::Error`) keep the existing diagnostic behavior. **Related issue:** - https://github.com/web-infra-dev/rspack/issues/14517
