refactor(traverse): move code generation from JavaScript to Rust Move the traverse crate's code generation scripts from `crates/oxc_traverse/scripts/` to `tasks/ast_tools/src/generators/traverse.rs`, rewriting them in Rust. This change: - Creates a new `TraverseGenerator` in ast_tools that generates: - `traverse.rs` - The `Traverse` trait with enter/exit methods - `ancestor.rs` - The `Ancestor` enum and related types - `walk.rs` - The `walk_*` functions for AST traversal - Removes the old JavaScript-based code generation (build.rs and scripts/) - Filters types to only include those from `oxc_ast/src/ast/` module - Generates offset constants only for structs with visited fields Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
