refactor(swc): make the primary compilation path linear Add Compiler::compile and compile_with_hooks for an explicit resolve-config, parse, transform, minify, finalize, and codegen pipeline. Route process_js_file and the default Node and wasm transform paths through it. Keep build_as_input and delayed pass construction isolated in the frozen legacy path for bundler and custom-pass compatibility. Preserve existing configuration and legacy API behavior.

ci: update rust-toolchain action pin (#12021) **Description:** The `GitHub Actions Security` workflow on `main` has been failing because `dtolnay/rust-toolchain` force-updated its `stable` branch. The previously pinned commit is no longer reachable from the branch history, so zizmor reports `commit with no history in referenced repository` for all 16 uses. Update every `dtolnay/rust-toolchain` reference to the current commit of the `stable` branch. This restores the online zizmor audit while retaining immutable action pins. Validated with: - `actionlint 1.7.12 -shellcheck=` - `pinact 3.9.0 run --diff --check --verify` - `zizmor 1.25.2 --persona regular --min-severity medium --min-confidence high` - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` **Related issue (if exists):** None.

fix(es/transforms/base): preserve parens around PURE-annotated receivers When paren_remover unwraps `(/* @__PURE__ */ new Set(x))` inside a MemberExpr, the leading annotation ends up attached to the inner expression. Without the surrounding parens, downstream tools (Rollup, esbuild, minifiers) interpret the annotation as applying to the entire chained call, which can cause `.forEach(cb)` and other side-effecting calls to be dropped by DCE. The fixer now detects a leading `@__PURE__`, `#__PURE__`, or `@__NO_SIDE_EFFECTS__` annotation on the object of a MemberExpr and wraps it in a ParenExpr whose span is dummy so that the annotation is emitted inside the parens.

feat(wasm): add @swc/nodejs-support-wasm (#11975) **Description:** Adds an independent Rust/WebAssembly binding at `bindings/binding_nodejs_support_wasm`, published as `@swc/nodejs-support-wasm`. The package has its own Rust crate, sources, build scripts, tests, README, Cargo entry, and npm workspace entry. It does not build from `binding_typescript_wasm` and does not add features or exports to the existing `@swc/wasm-typescript` or `@swc/wasm-typescript-esm` packages. The new CommonJS package embeds its wasm binary and exposes these APIs at the top level: - `transform` - `transformSync` - `transformModuleSyntax` - `getFirstExpression` - `isValidSyntax` - `isRecoverableError` It also exports the related `Options`, `TransformOutput`, and `ModuleSyntaxTransformOutput` TypeScript types. The npm publish matrix, wasm CI matrix, release versioning, Cargo lockfile, and pnpm lockfile now reference the standalone `binding_nodejs_support_wasm` crate. Validation performed: - `git submodule update --init --recursive` - `cargo fmt --all -- --check` - `cargo test -p binding_typescript_wasm -p binding_nodejs_support_wasm` - `cargo clippy --all --all-targets -- -D warnings` - `(cd bindings/binding_nodejs_support_wasm && ./scripts/test.sh)` - `(cd bindings/binding_typescript_wasm && ./scripts/test.sh)` - `(cd bindings/binding_core_wasm && ./scripts/test.sh)` - `(cd bindings/binding_minifier_wasm && ./scripts/test.sh)` - `(cd bindings/binding_es_ast_viewer && ./scripts/test.sh)` - `(cd bindings/binding_nodejs_support_wasm/pkg && npm pack --dry-run --json)` - `pnpm install --frozen-lockfile --ignore-scripts` - `go run github.com/rhysd/actionlint/cmd/actionlint@latest .github/workflows/CI.yml .github/workflows/publish-npm-package.yml` **BREAKING CHANGE:** None. The existing TypeScript wasm packages and their public APIs are unchanged. **Related issue (if exists):** - Supports nodejs/node#64034 - Follow-up context from swc-project/swc#11973
