Fix security vulnerability in wasmtime dependency Upgrade wasmtime from v35.0.0 to v38.0.4 and wasi-common from v35 to v38 to address security vulnerability RUSTSEC-2025-0118 (unsound API access to WebAssembly shared linear memory). This resolves the failing "Check license of dependencies" CI check. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Remove obsolete advisory IDs from deny.toml Remove RUSTSEC-2020-0071 and RUSTSEC-2020-0159 from the ignore list as these advisories are no longer encountered in the current dependency tree. This fixes the cargo-deny advisory check failure. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

fix(ecma_transformer): Add explicit swc_atoms import for cargo-shear This commit adds an explicit import of swc_atoms::Atom to make the dependency usage visible to cargo-shear. Previously, the dependency was used implicitly through the Into trait conversion, which cargo-shear could not detect. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

fix(ecma_transformer): Remove unused dependencies from Cargo.toml This commit removes unused dependencies (bitflags and tracing) from the swc_ecma_transformer crate to fix cargo-shear CI check failures. The crate only uses: - rustc-hash: For FxHashMap in TraverseCtx - swc_atoms: For Atom creation - swc_common: For SyntaxContext - swc_ecma_ast: For AST types - swc_ecma_hooks: For VisitMutHook trait - swc_ecma_visit: For VisitMut trait 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Fix test compilation errors in swc_ecma_transformer Fix the test_add_hook test that was failing to compile because unit type () does not implement VisitMutHook<TraverseCtx>. Changed the test to use proper test hook implementations (FirstHook and SecondHook) that implement the trait. This resolves the CI clippy and check failures. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

feat(ecma_transformer): Set up foundational crate for VisitMutHook-based architecture This commit establishes the foundational structure for the swc_ecma_transformer crate, which will be used to port oxc transformer implementations to SWC's VisitMutHook-based architecture. ## Changes ### Core Architecture - **TraverseCtx**: Context struct for sharing state across transformations - Tracks scope depth, ancestor nodes, and identifier metadata - Provides helper methods for common operations - Inspired by oxc's TraverseCtx but adapted for SWC - **Transformer**: Main transformer struct that implements VisitMut - Delegates to child hooks via VisitMutHook trait - Supports composing multiple transforms via CompositeHook - Uses HookAdapter internally to properly forward visitor calls ### Dependencies - swc_ecma_ast: Core AST types - swc_ecma_visit: Visitor trait - swc_ecma_hooks: VisitMutHook trait implementation - swc_common: Common utilities - rustc-hash: Fast hashing for identifier tracking - bitflags, tracing: Supporting utilities ### Design Principles - Single-pass transformation: All transforms run in one AST traversal - Composability: Transforms can be composed using CompositeHook - Type safety: Hook system ensures correct composition at compile time - Shared context: TraverseCtx provides state sharing across transforms ### Future Work This crate provides the foundation for implementing ES20xx and TypeScript transforms as composable hooks. Individual transform implementations will be added in subsequent commits. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
