/**
 * PiHarness — CodingHarness implementation for the pi coding agent.

 * This harness encapsulates the existing pi-specific spawning logic:

 * - Launch command construction with --session-id, --model, --provider, etc.
 * - Readiness detection via the pi-ready-signal extension
 * - JSONL session file monitoring (reuses existing session-parser logic)
 * - Temp directory cleanup on teardown
