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) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
