feat(ccw): migrate backend to TypeScript

- Convert 40 JS files to TypeScript (CLI, tools, core, MCP server)
- Add Zod for runtime parameter validation
- Add type definitions in src/types/
- Keep src/templates/ as JavaScript (dashboard frontend)
- Update bin entries to use dist/
- Add tsconfig.json with strict mode
- Add backward-compatible exports for tests
- All 39 tests passing

Breaking changes: None (backward compatible)
