feat: dream-cycle merge scan + pattern desk (leak recall)

Phases 5 & 6, completing the scouting desk.

Phase 5 — the nightly consolidation (dream cycle, coherence block) now runs
poker.scan_merge_candidates(), filing likely same-person merges to the review
queue off the hot path. Fail-safe: a scan error never sinks the cycle.

Phase 6 — "you've hit this leak before". Scar/confidence notes are embedded on
write; recall_similar_rituals() finds past ones close to the current spot,
excluding tonight. The scouting desk adds a pattern pass that surfaces them — but
ONLY on genuine strategy/tilt talk (a length + cue gate), so routine logging like
"stack 350" never pays for an embed. Respects the per-turn latency concern.

7 tests (deterministic embed stub to keep threshold assertions stable). Full
suite 153 green.
