Cancel in-flight blockfetch when the owning connection closes, preventing
permanent pipeline stalls from orphaned chainsyncBlockfetchReadyChan.

Purge seenHeaders dedup cache when clearing queued headers and when
releasing the pipeline owner on chain switch, so the new connection can
re-deliver headers that were previously deduplicated against the old owner.

Guard rollback-to-current-tip as a no-op to avoid spurious resync events.
Retry blockfetch on alternate connections when the initial connection fails.
Track batchBlocksReceived across flush cycles for accurate empty-batch
detection. Add debug-level diagnostic logging at pipeline chokepoints.

Large chain rollbacks produced BadgerDB "Txn is too big" errors when
deleting many blob entries in a single transaction. Split deletes into
batches of 5000 keys per transaction.

BuildKit mount caches caused stale object files during rapid iteration,
producing binaries that didn't reflect the latest source changes.
