fix(bindings): fall back to a secure Windows profile cache (#12452) **Description:** Windows native binding loading can fail when the default LocalAppData cache inherits writable AppContainer permissions. The same failure affects `SWC_NATIVE_BINDING_CACHE=0`, since temporary loading uses the default cache root. Retry cache failures from `%LOCALAPPDATA%\swc` in `%USERPROFILE%\.swc-cache`, using the existing owner, ACL, and reparse-point checks. Apply the same fallback to default loading, temporary loading, and default loading after a custom cache fails. Keep temporary files unique and preserve their cleanup behavior. Explicit `cached_at` calls retain their specified root, and integrity failures remain fatal. Report both attempted locations and their causes when fallback fails, log retries with structured diagnostics, and document the Windows path order. Add isolated Windows ACL and cache fixtures plus real Node carrier coverage for concurrent loading, reuse, corruption recovery, callbacks, cleanup, and preservation of the original root ACLs. **Validation:** - On macOS: `cargo fmt --all`, `cargo clippy --all --all-targets -- -D warnings`, tests for `swc_native_addon`, `swc_native_addon_pack`, and `binding_native_addon`, and the private-crate Rust 1.73 MSRV suite passed. - `packages/core`: `pnpm build:dev && pnpm test` passed (119 tests passed, 3 skipped). - [Carrier lifecycle CI](https://github.com/swc-project/swc/actions/runs/36813599959) passed on Windows x64, Windows ARM64, macOS, and Linux at implementation commit `c2bb98d7cb219bec35bfb0c6528a7adb3c900558`, including Windows ACL/cache fixtures, real Node loading, cleanup, and the x64 Rust 1.73 checks. The subsequent commit only adds the changeset. **Related issue (if exists):** Fixes #12442

fix(es/preset-env): lower for-await in native async functions (#12414) **Description:** Fix preset-env compilation for targets that support ordinary async functions but not async iteration, such as Chrome 60. `for await` loops inside ordinary async functions, methods, and async arrows now lower to iterator code with native `await`, while the surrounding functions remain async. Preserve lexical `this`, `arguments`, and `super` across nested async arrows, and keep existing full async lowering and native async-iteration behavior. **BREAKING CHANGE:** None. **Related issue (if exists):** Fixes #12399 **Tests:** - `cargo test -p swc_ecma_preset_env` - `cargo test -p swc_ecma_transformer` - `PATH="$PWD/node_modules/.bin:$PATH" cargo test -p swc_ecma_transforms_compat --test es2017_async_to_generator` - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings`

chore(ci): ignore unused Wasmtime component advisory (#12453) **Description:** The dependency-check job fails on `RUSTSEC-2026-0316` for Wasmtime 38.0.4. Add an advisory-specific exception with a comment explaining why the affected path is unused: `swc_plugin_backend_wasmtime` disables `component-model` and runs core Wasm modules with integer host calls, while the advisory concerns dynamic record lifting through `wasmtime::component::Val`. Wasmtime 38 has no patched release. This follows the existing policy for that dependency line, and the comment calls for revisiting the exception when upgrading the backend. Validation: - Reproduced the reported failure with the original `deny.toml` using cargo-deny 0.18.9. - `cargo deny check` passes all four checks with the updated configuration. - `cargo tree -p wasmtime -e features --invert --depth 2` confirms `component-model` is not enabled. - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` Only CI policy changes; no Rust crate or dependency versions change, so no release changeset is needed. **BREAKING CHANGE:** None. **Related issue (if exists):** Fixes the [dependency-check failure](https://github.com/swc-project/swc/actions/runs/36817448595/job/110225759786?pr=12414) observed in #12414. Upstream advisory: https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-jqpg-j7w6-42pr
