fix(p2p): request messages for an explicit block and round

[oXtxNt9U]

Summary

GetMessages requests now carry an explicit (blockNumber, round, bitmaps) query instead of the responder guessing from the request headers. The responder serves exactly the queried round or nothing.

• removes timing races where honest replies were judged against a moved target and peers wrongly banned
• query bitmaps are copied at job creation so they can't drift while the request waits
• precommit minorities now also trigger full downloads, matching the consensus rule
• incomplete replies are logged instead of banned (not provable misbehavior)
• payload limit scales with validator count

Checklist

• Documentation (if necessary)
• Tests (if necessary)
• Ready to be merged
