feat: transform to agent coordination platform with comprehensive documentation

Transform Issue Facade from a universal CLI tool into an agent coordination platform with comprehensive documentation and enhanced capabilities for autonomous coding agents.

Major Changes:
- Complete README rewrite focusing on agent-driven coordination
- New comprehensive documentation (AGENT_INTEGRATION.md, CLAUDE.md, ROADMAP.md)
- Capability integration setup with CAPABILITY.yaml and integration scripts
- Enhanced Makefile with local development targets for easier workflows

Bug Fixes:
- Fix schema initialization using executescript() for multi-line SQL support
- Disable FTS5 triggers due to compatibility issues (documented for future re-enablement)

Features:
- Enhanced CLI list command with full parameter passthrough
- New examples directory with agent integration patterns
- New comprehensive test suite (test_core_models.py, test_local_backend.py)

Code Quality:
- Remove @cached_property decorators for Label properties (simplification)
- Clean up test organization (removed old test_gitea_integration.py)

This milestone establishes Issue Facade as a production-ready coordination layer for multi-agent software development, with clear integration paths and comprehensive developer documentation.
