Earlier breaking changes
- v3.13.0 Section without an operator is now treated as OR instead of AND; migration not reversible.
- v3.13.0 Per-group exclusions now apply only to their own group, not globally.
- v3.13.0 Exclusions are now either global or per-group; removing a global exclusion requires re-adding per-group ones.
- v3.12.1 Renames `WATCH_HISTORY_CONCURRENCY` to `RULE_EVALUATION_CONCURRENCY` for clarity.
- v3.11.0 Overlay reset operations are now gated against concurrent processing runs.
