- **New Features**
- Added configurable QoS snapshot compaction to periodically reclaim storage from expired snapshots.
- Compaction runs daily by default and can be disabled by setting the interval to `0`.
- QoS config hot-reload now recognizes compaction interval changes.
- Older saved snapshot checkpoints remain compatible with the new setting.
- **Documentation**
- Updated configuration examples and reverse-proxy QoS documentation to include `compaction_interval_secs`, its default, and disable behavior.
Shared HLS cache session feature and aligns the runtime, cache, provisioning, recovery, custom-response, and documentation paths with the new shared-session model.
