reconstruct and build @anthropic-ai/claude-code source from source map

- Extract 4756 source files from cli.js.map (57MB)
- Set up Bun build system with bun:bundle feature flag shim
- Configure 90+ compile-time feature flags matching production defaults
- Inject MACRO constants (VERSION, BUILD_TIME, etc.)
- Create stubs for private packages (color-diff-napi, modifiers-napi, etc.)
- Install all public dependencies via pnpm
- Patch commander v14 to allow multi-char short flags (-d2e)
- Build output: dist/cli.js (22MB), verified working
