/**
 * v0.3.0 — read Claude Code's own session jsonl files.
 *
 * Used by workflow-reconciler.ts when the bot crashed after a PM message
 * was processed (claude wrote the assistant reply to its jsonl) but
 * before the messenger pipe got to deliver it. We re-emit the most
 * recent assistant turn so the user sees the reply on bot restart.
 *
 * Couples us to Claude Code's internal jsonl format — keep it defensive.
 * Every helper here returns null on any parse/structure miss instead of
 * throwing.
 *
 * Per docs/plan/v0.3-pm-mode-orchestration.md §3.2 + RECOVERY-AND-TEST-DESIGN.md §3.4.
