Reduces onboarding to `npm install -g @composio/ao && ao start`.
- Absorb init and add-project logic into `ao start` with auto-config
creation, environment detection, and project type detection
- Add single-instance tracking via running.json with already-running
interactive menu (human) and info+exit (agent)
- Add caller context detection (human/orchestrator/agent) via TTY and
AO_CALLER_TYPE env var
- Add plugin-based agent runtime detection — no hardcoded binary paths,
each plugin exports detect() and displayName
- Simplify `ao spawn` to just `ao spawn <issue>` with auto-detected
project (backward compat: `ao spawn <project> <issue>` still works)
- Set AO_CALLER_TYPE, AO_PROJECT_ID, AO_CONFIG_PATH, AO_PORT env vars
on all spawned sessions (worker, orchestrator, restore)
- Add `ao config-help` subcommand for config schema reference
- Deprecate `ao init` to thin wrapper, fully remove `ao add-project`
- Register/unregister in running.json on start/stop
