chore: complete TypeScript migration (Phase 05-06)

Phase 05: Migrate test imports from bin/ to dist/
- Update 19 test files to import from dist/ instead of bin/
- Update CLI path in cli.test.js and special-commands.test.js
- Update cross-platform.test.js to check dist/ directory

Phase 06: Cleanup & validation
- Remove bin/ directory (32 JS files)
- Fix ClaudeSymlinkManager import in doctor.ts
- Update postinstall.js to use dist/ modules
- Regenerate package-lock.json (now points to dist/ccs.js)

All 39 tests passing. TypeScript migration complete.
