/**
 * Pi extension factory. Wires the steering engine onto pi's
 * lifecycle events.
 *
 * Strict-mode contract: see {@link SteeringConfig.failOnWarnings}.
 *
 * Lifecycle wiring:
 *
 *   - factory time      — eager load via {@link buildSessionRuntime};
 *                         throws on diagnostic per the strict-mode
 *                         contract.
 *   - `agent_start`     — bump the internal `agentLoopIndex` counter
 *                         so tool_call / tool_result handlers can
 *                         forward it into the evaluator + dispatcher.
 *                         One agent loop = one user prompt + all the
 *                         tool calls it spawns.
 *   - `session_start`   — emit a `console.warn` if the resumed
 *                         session's `ctx.cwd` differs from the launch
 *                         cwd captured at factory time (cross-project
 *                         resume). The engine continues evaluating
 *                         with launch-cwd rules.
 *   - `tool_call` / `tool_result` route through the evaluator and
 *     dispatcher (see {@link buildSessionRuntime}).
 *
 * Exported as the default export per pi's extension convention.
