feat: standardise recheck availability to JSONL output

- extract_recheck() now writes availability_{date}_recheck_{HH}.jsonl.gz
  (one venue per line with date/captured_at_utc/recheck_hour injected);
  uses compress_jsonl_atomic; removes write_gzip_atomic import
- stg_playtomic_availability: add recheck_jsonl CTE (newline_delimited
  read_json on *.jsonl.gz recheck files); include in all_venues UNION ALL;
  old recheck_blob CTE kept for transition
- init_landing_seeds.py: add JSONL recheck seed alongside blob seed
- Docs: README landing structure + data sources table updated; CHANGELOG
  availability bullets updated; data-sources-inventory paths corrected
