feat(dbg-swc): add flow strip verification command (#11706) ## Summary - add a new Flow debug command group under `dbg-swc es flow` - add `dbg-swc es flow strip <path>` to verify Flow strip behavior for user-provided file/directory inputs - map Flow parser options from CLI flags (`--jsx`, `--all`, `--require-directive`, `--enums`, `--decorators`, `--components`, `--pattern-matching`) - run per-file verification pipeline: parse as Flow -> strip -> emit -> reparse as ES -> check `__flow_` leakage - collect all failures and print stage-based summaries (`parse`, `strip`, `reparse`, `leak`) before returning non-zero - add unit tests for flag mapping, recursive `.js/.jsx` collection, and a minimal Flow strip success case - enable `flow` feature for `swc_ecma_parser` and add `swc_ecma_transforms_typescript` dependency in `dbg-swc` ## Testing - `cargo fmt --all` - `cargo test -p dbg-swc` - `cargo clippy --all --all-targets -- -D warnings` - `cargo run -p dbg-swc -- es flow strip --help` - `cargo run -p dbg-swc -- es flow strip crates/swc/tests/fixture/flow-strip/input` - `cargo run -p dbg-swc -- es flow strip crates/swc/tests/fixture/flow-strip/input/index.js --jsx`

fix(es/flow): normalize module await bindings for Hermes parity (#11703) ## Summary - Normalize module-level `await` bindings after TS/Flow strip in `swc_ecma_transforms_typescript`. - Apply renaming via `swc_ecma_transforms_base::rename::rename` with collision-safe names (`_await`, `_await1`, ...). - Preserve exported API names (e.g. `await`) through export-specifier rewriting behavior in the renamer. - Remove stale entries from `crates/swc_ecma_parser/tests/flow-hermes/known-fail-strip.txt`. ## Why `flow_strip_hermes` had 2 remaining failures where stripped output still emitted invalid module identifiers: - `async_await/migrated_0020.js` - `async_await/migrated_0024.js` This change makes strip output reparsable as ES while keeping external export names stable. ## Testing - `git submodule update --init --recursive` - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` - `cargo test -p swc_ecma_parser --test flow_hermes --features flow -- --nocapture` - `cargo test -p swc --test flow_strip_hermes --features flow -- --nocapture` - `cargo test -p swc_ecma_parser --features flow` - `cargo test -p swc_ecma_transforms_typescript --test strip -- --skip issue_960_2` Note: - `cargo test -p swc_ecma_transforms_typescript` includes an environment-dependent failure (`issue_960_2`) when `mocha` is unavailable.
