BandwidthOptimizer

#### v2.8.11.29-release

Important fixes:
1. Fixed proxy server-switch reset windows so stale transport frames and PLAY payloads no longer cross into the new backend login or chunk stream.
2. Fixed player floating after TP triggered by reset-style mods.
3. Fixed chunk restore stalls during fast map traversal.
4. Reduced player TP chunk-load latency; the BO path can now reach a usable state faster than vanilla loading in tested cases.

Other fixes:
1. Added sender-side limits for batch and single transport carriers to prevent frames that the receiver would reject.
2. Fixed streaming carrier frame smuggling and bad-carrier state poisoning.
3. Improved persistent manifest and chunk cache synchronization, refresh, and restore stability.
4. Improved Create dynamic-structure block entity bypassing and TP critical-path protection.
5. Fixed server HUD session bandwidth accounting so live stats no longer include persisted historical totals.
