perf(semantic): make CFG construction a compile-time feature (#13678) part of #13646 ## Summary This PR converts the Control Flow Graph (CFG) functionality in `oxc_semantic` from runtime checks to a compile-time cargo feature, eliminating runtime overhead when CFG is not needed. ## Changes - Added `cfg` cargo feature to `oxc_semantic/Cargo.toml` with `oxc_cfg` as optional dependency - Feature-gated all CFG-related code using `#[cfg(feature = "cfg")]` - Updated `oxc_linter` to enable the `cfg` feature (since it requires CFG) - Made the `control_flow!` macro work correctly with and without the feature ## Benefits - **Performance**: Eliminates runtime `Option<CFG>` checks when feature is disabled - **Binary size**: Smaller binaries for crates that don't need CFG - **Cleaner API**: CFG methods only available when feature is enabled ## Test Plan - [x] All existing tests pass with `cargo test -p oxc_semantic --features cfg` - [x] `oxc_linter` builds and works correctly (it enables the feature) - [x] Feature is backward compatible - existing code continues to work 🤖 Generated with [Claude Code](https://claude.ai/code)
