/**
 * v2.11.0 Group F (Tier 9) — D7: post-compact auto-resume detector.
 *
 * Per `.peaks/memory/2026-06-26-v2-11-post-compact-resume.md` §D7.a,
 * post-compact auto-resume triggers when ALL of the following hold:
 *
 *   1. `.peaks/_runtime/<sessionId>/` is bound
 *   2. Latest checkpoint mtime is from today (UTC date)
 *   3. Latest checkpoint has a parseable `mode` field
 *   4. The peak-code skill is the active skill
 *   5. Exactly one session has a today's checkpoint (no ambiguity)
 *
 * On a hit, the LLM MUST auto-resume (D7.b override of "never silently
 * auto-resume") and emit a one-line log entry. On any miss, fall
 * through to the normal Step 0.7 flow.
 *
 * Karpathy §3: the detector is the only place that decides "is this
 * a post-compact resume?" — no inline `isPostCompact()` checks
 * scattered across SKILL.md or other services.
 *
 * IO: readdir + readFile on `.peaks/_runtime/<sid>/checkpoints/`.
 * No writes (caller logs the decision via the auto-decisions channel).
