feat: 3P replication fall-back and resilience

[cdata]

This change proposes the following:

• A "fall back to local data" strategy for peers with new versions that fail to replicate
• Per-block latency guards on CAR streams to detect stalled Kubo queries
• Secondary Kubo pinning for orphaned blocks in Noosphere CAR streams
• Timeouts when looking blocks up from Kubo have been reduced (net ~16s to net ~10s)
• Improvements to car example utility to report orphaned or missing blocks in a CARv1
