feat: fully implement ghost-mcp server

- Fixed Dockerfile to skip prepare script during npm ci
- Changed docker-compose.yml to use node:22-alpine image with npx
- Updated STATUS.md to mark ghost-mcp as Built
- Added ghost-mcp to crush.json for Crush integration
- Validated container starts correctly with proper Ghost credentials

The ghost-mcp server now works as expected using the @fanyangmeng/ghost-mcp
npm package. It requires GHOST_API_URL and GHOST_ADMIN_API_KEY in the
format {24_hex_chars}:{64_hex_chars}.
