This commit adds 6 new documentation files to fill critical gaps:
- CONTRIBUTING.md: Developer onboarding guide with setup, workflow,
code style, testing, and adding features
- TROUBLESHOOTING.md: Common issues and solutions for errors,
model issues, tool issues, channel issues, gateway issues,
configuration issues, and memory/database issues
- docs/api/PROTOCOL.md: Gateway JSON-RPC protocol documentation
with connection, authentication, message format, methods,
events, error codes, and example client implementation
- docs/api/TOOLS.md: Tools API documentation covering tool interface,
input schema format, result format, tool patterns,
tool registration, tool policy, execution flow, and
builtin tools reference
- docs/deployment/PRODUCTION.md: Production deployment guide
covering Docker deployment, systemd service, security,
configuration, monitoring, backup & recovery, and
performance tuning
- docs/performance/TUNING.md: Performance optimization guide

performance, gateway performance, and resource usage
These files complement the existing excellent documentation
(README.md, AGENTS.md, ARCHITECTURE.md, STRUCTURE.md,
CONVENTIONS.md) to provide complete coverage for users,
developers, and operators.
