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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
