pi-coding-agent 0.70 replaced the mutable \`AgentState.error\` field with
a readonly \`AgentState.errorMessage\`. \`session.prompt()\` still does
not throw when retries are exhausted, so we still need to re-raise the
stored error after each prompt.
- checkSessionError (usage-limit-detector): widen parameter to accept
either key; prefer errorMessage so new sessions work, fall back to
error so we can deploy without forcing everyone's caches to rebuild.
- agent-reflection: same widening at the call site.
- pi.ts helpers: read both keys, best-effort clear both (the new field
is readonly, so the write is a no-op on 0.70 sessions but still
matters for mock sessions in tests).

- Rename engine export and call sites to use createFnAgent consistently across runtime flows
- Update core lazy engine loader and dashboard agent-generation/planning/chat paths to reference createFnAgent
- Refresh affected unit and integration tests, including renaming pi-create-kb-agent.test.ts to pi-create-fn-agent.test.ts
- Update AGENTS.md documentation references to match the new createFnAgent name
- Extend project settings with reflection enablement, interval, and post-task trigger defaults
- Implement AgentReflectionService to gather agent/task history, generate structured AI reflections, and persist reflection metrics
- Add reflect_on_performance tool factory with optional focus area input and human-readable reflection output
- Wire reflection tool into TaskExecutor only when reflection is enabled and the task has an assigned agent
- Add comprehensive reflection service/tool tests and stabilize agent-store org tree expectation ordering
