pi-rnd v0.2.2

- Fix race in /rnd-doctor round-trip lifecycle listener (was registered after spawn RPC, missing subagents:started)
- Drop bogus subagents:created listener (not emitted on RPC spawn path per pi-subagents source)
- Improved diagnostic: distinguish 'agent never transitioned to running' from 'agent started but LLM hangs'
- Drop max_turns from 3 to 1 for the round-trip probe (single LLM call, faster predictable test)
- Add project CLAUDE.md with session learnings
