feat: add jiron-discovery, vibe-generate, and vibe-publish modules

Add API discovery, code generation, and publishing modules:

jiron-discovery:
- API contract discovery from Jiron endpoints
- Schema extraction and validation
- Endpoint metadata collection

vibe-generate:
- AI-powered code generation
- Template-based output formatting
- Multi-file generation support

vibe-publish:
- Capsule packaging and upload
- Authentication retry with token refresh
- Progress tracking and error handling

Depends on: vibe-utils (#73), vibe-auth (#74), vibe-prompt (#75)
