Capture team chat and expose moderation match archives

 Unarchived or already deleted chat cannot be attached as verified evidence.
 
+Open **Chat archive** from Moderation to include all recorded matches, including
+round-one games, interrupted games, and games missing an end report. Archive
+access requires moderation read permission. Filter by server, game, map, status,
+or date and open a match to select its preserved messages. Incomplete matches
+show their observed state rather than final results. Ordinary match history and
+leaderboard qualification are unchanged.
+
+Both public (`say`) and team (`sayteam`) log messages are captured. Team messages
+carry a **Team chat** label in chat and saved excerpts. Collection runs without a live
+viewer and checks surviving logs once after startup, including idle servers.
+Archive coverage still depends on the source log and accepted match telemetry:
+logs that were deleted or rotated before collection, or old clock segments that
+cannot safely be associated with a match, cannot be reconstructed. The collector
+retains a bounded log tail (up to 2,000 lines / 256 KiB); it is not a full historical
+log import. Already saved case excerpts survive later source cleanup.
+
 Case decisions, edits, and restrictions check the current revision; refresh before
 retrying a decision if another staff member has changed the case. Evidence,
 restrictions and append-only moderation events survive source-match cleanup and
