Details

Park the expert bot on the configured tournament server (default
http://141.37.123.132:8086) on startup, reusing a fixed
TOURNAMENT_BOT_TOKEN when present instead of minting a new identity.

feat(analytics): feed Lichess PGN dumps into Spark batch jobs

Build & Test (NowChessSystems) TeamCity build failed

Details

6351a19b67

Add GameSource: normalises game records into a shared schema and
selects backend via NOWCHESS_PGN_PATH. Unset = PostgreSQL game_records
(unchanged); set = a Lichess PGN dump (file or http(s) URL).

- Parse Lichess PGN with Spark SQL string functions only (no UDFs).
- URLs fetched once via SparkContext.addFile, distributed to executors.
- .pgn.zst decompressed in-process via zstd-jni, plain .pgn redistributed.
- All four batch jobs read through GameSource and skip JDBC write-back
  in PGN mode (Parquet/CSV output only).

Enables driving the analytics demo straight from
https://database.lichess.org standard dumps.
