* Originate v2 source routes and wire fragmentIdFilter targeted resync
Part A — source-route origination policy:
- Gate route application (BLESourceRouteOriginationPolicy): only packets we
author, directed at a single peer, with TTL headroom, whose recipient is
not directly connected. Relays no longer attach routes to (and re-sign)
packets they merely forward.
- Version-gate paths: MeshTopologyTracker records the highest protocol
version observed per peer; BFS routes require every intermediate hop and
the recipient to be v2-observed, capped at 4 intermediate hops.
- Degrade on failure: BLESourceRouteFailureCache marks a routed send that
sees no inbound traffic from the recipient within 10s as failed and floods
for 60s before retrying routes.
Part B — REQUEST_SYNC fragmentIdFilter (TLV 0x06):
- Requester: BLEFragmentAssemblyBuffer reports stalled broadcast
reassemblies (no new fragment for 5s, retried at most every 10s); the
maintenance pass sends a types=fragment REQUEST_SYNC naming the stalled
8-byte fragment stream IDs to each connected peer.
- Responder: GossipSyncManager restricts the fragment diff to exactly the
named streams, bypassing the since-cursor while the GCS filter still
excludes pieces the requester holds; RSR/TTL-0/rate-limit semantics
unchanged and REQUEST_SYNC stays link-local.
- Bounds: at most 60 IDs per request (60*17-1 = 1019 bytes <= the 1024-byte
decoder cap); oversized 0x06 values are ignored, not fatal.
Docs: SOURCE_ROUTING.md gains the iOS origination policy (§8);
REQUEST_SYNC_MANAGER.md documents 0x05/0x06 as implemented.

* Fix stall-clock refresh on duplicates and overflow suppression in fragment resync
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.
