This adds automatic detection and bundling of Worker files when they are
referenced via `new Worker("./path.ts")` with a string literal.
Changes:
- Add ImportKind.new_worker to track worker imports separately
- Detect `new Worker(path)` pattern in the AST visitor (visitExpr.zig)
- Store worker_import_record_index in E.New AST node
- Add worker files as entry points in LinkerGraph.zig
- Rewrite worker paths to bundled chunk paths in printer (js_printer.zig)
- Handle worker path rewriting even without code_splitting
Worker detection is limited to:
1. Global unbound Worker (Bun's Web Worker API)
2. Worker imported from 'node:worker_threads' or 'worker_threads'
User-defined classes named Worker are NOT detected to avoid false positives.
This allows workers to be automatically bundled without needing explicit
entryPointsRaw configuration.
