Replaces the AZ-305 pass-through _evaluate_freshness hook with the production FreshnessGate. Loads tile_freshness_rules + sector classifications once at construction, builds an rtree index, and on every evaluate() either returns metadata unchanged (FRESH), stamps freshness_label=DOWNGRADED (stable_rear + stale), or raises FreshnessRejectionError carrying tile_id / age_seconds / classification / rule diagnostics (active_conflict + stale). Constructed inside PostgresFilesystemStore.from_config; the public storage_factory signature is preserved so AZ-305 unit tests still build the store with freshness_gate=None for the pass-through path. FDR schema bumped to v1.2.0: adds c6.freshness.rejected and c6.freshness.downgraded kinds (non-breaking; v1.1 readers route them opaquely). Operator CLI `python -m c6_tile_cache.freshness_gate explain` dry-runs the decision for a (lat, lon, capture_ts). Adjacent hygiene: c6_tile_cache.tools._dump_tile now passes os.environ to load_config (AZ-305 regression — load_config requires the env mapping). Co-authored-by: Cursor <cursoragent@cursor.com>
