fix(react-compiler): add files allowlist so publish includes entrypoints Without a "files" field, npm falls back to .gitignore/.npmignore to decide what to publish, and the combination of both in this package excludes binding.js/binding.d.ts/index.js/index.d.ts entirely — verified via `npm pack --dry-run` that the tarball shipped only tests/config, no usable code. Mirrors the explicit files allowlist packages/core already uses to avoid this.

ci: split react-compiler build/test into its own job Per review feedback, the react-compiler build/test steps were piggybacking on the node-test job. Give them a dedicated job so they run independently.

fix(es/react-compiler): Correct catch and parameter scope resolution (#11985) **Description:** Fixes React Compiler scope conversion for catch and parameter bindings. The bug from #11982 was exposed by compiling an async `useCallback` with `catch (error) { return error; }`: the converted scope info did not consistently model the catch parameter as a value binding, so references to the catch value could be left unresolved and produce incorrect compiled output. This PR updates `SemanticBuilder` so declaration-space flags carry value-ness explicitly, with marker flags (`Param`, `CatchVariable`, `FunctionExpression`) layered onto value-bearing flags. Catch bindings stay in the catch scope and can be resolved from catch bodies and catch parameter initializers. It also models parameter initializers and destructuring patterns with a temporary internal resolution scope. Function, arrow, constructor, accessor, and catch parameters now resolve references before body bindings are collected, so defaults and computed pattern keys observe the intended lexical visibility: function expression names and parameter bindings are visible, while body bindings do not shadow parameter initialization. These internal parameter scopes are skipped when emitting React Compiler `ScopeInfo`, preserving the public scope tree. Coverage includes: - the async `useCallback` catch-binding compile-pass fixture for #11982 - catch destructuring with computed keys and initializer references - function parameter defaults resolving to outer bindings, later parameters, or named function expressions - named function expressions shadowed by params or body `var` declarations **Related issue:** - Closes #11982

fix(es/react): Emit jsxdev source for fragments (#11993) **Description:** Fixes JSX development transform output for shorthand fragments. Previously, JSX fragments transformed with `_jsxDEV` did not receive source metadata, so React dev tooling could not report the correct fragment location. This PR makes fragment `_jsxDEV` calls include the same source argument as JSX elements. It also reuses the existing `jsx_self` constructor guard through a shared `JsxSelfCtx`, so fragments only emit `this` as the self argument when it is safe. In derived class constructors, fragments now use `void 0`, matching the existing JSX element behavior. Added fixture coverage for: - JSX fragment source metadata regression from #11990 - fragment self handling inside derived class constructors Verified with: - `cargo fmt --all` - `cargo test -p swc_ecma_transforms_react` - `cargo test -p swc_ecma_transforms_react issue_11990 -- --ignored` - `cargo test -p swc_ecma_transforms_react jsxdev_fragment_derived_constructor -- --ignored` - `cargo clippy --all --all-targets -- -D warnings` **Related issue:** - Closes #11990
