- Bumped Erlang baseline to 25; nodes on older Erlang versions will fail to start (breaking compatibility).
- Added several core and plugin enhancements: in‑memory table compression for quorum queues, default queue‑type import, new effective‑config API, CLI help now respects global flags, and more.
- Fixed multiple bugs such as feature‑flags being disabled after restart, classic queues with single active consumer exceptions, CLI queue error formatting, and plugin boot failures.
