feat: make agent capabilities data-driven via agent YAML metadata

Replace the hardcoded getAgentCapabilities() map with a data-driven
pipeline. Capabilities are now defined in each .agent.yaml source file,
compiled into the XML output, extracted into agent-manifest.csv by the
manifest generator, and read by the GitHub Copilot handler at install
time. New agents automatically get their capabilities without code
changes.
