Two fixes to stalledBroadcastFragmentIDs bookkeeping in
BLEFragmentAssemblyBuffer:
- Duplicate fragments no longer reset the stall clock. Fragment packets
bypass the packet deduplicator, so relayed duplicates of an
already-held index arriving every few seconds kept lastFragmentAt
fresh and suppressed the targeted REQUEST_SYNC indefinitely. Now
lastFragmentAt only updates when the index is new (actual progress).
- Only the streams that will actually be encoded on the wire are
rate-limited. Previously every stalled candidate got
lastResyncRequestAt set, but encodeFragmentIdFilter serializes at most
RequestSyncPacket.maxFragmentIdFilterCount (60) IDs, so overflow
streams were suppressed for retryAfter without ever being requested.
Selection now caps at that shared constant, oldest stall first, so
overflow stays eligible and rotates fairly on the next pass.
Tests: duplicates arriving periodically still trigger the stall report;
70 stalled streams yield the 60 oldest on the first pass and the
remaining 10 on the next.
