- Restructure wal-cleanup.md: action-first layout (quick start, verify,
  integrate, troubleshoot, config reference)
- Fix incorrect claim that both trigger sources make cleanup less aggressive
  (code merges sources per instance, making it more aggressive)
- Fix boundary inclusivity: boundary entry is deleted (inclusive), not retained
- Fix recovery target: must be after boundary, not on-or-after
- Fix broken anchor in checkpoint.md (#integrating-with-the-sql-checkpoint-commands → #checkpoint-history)
- Add troubleshooting section with common operational scenarios
- Add "Verifying cleanup is running" section with log format reference
- Add prominent warning that cleaner needs N entries before acting
- Fix "recognise" → "recognize" for American English consistency
- Fix webpack alias for @questdb/sql-parser/grammar subpath export
- Fix pre-existing path.resolve("/node_modules/react") → use __dirname

The backup.window.count default is 5, meaning the cleaner retains data
needed by the 5 most recent backups/checkpoints. The boundary entry
itself is retained, with only older data deleted.
