PR intention
Fix a quorum signing correctness bug where a peer that sent an invalid lazy BLS sig-share could still have the rest of its collected sig-share batch processed as verified. This could let malformed or forged trailing shares poison local LLMQ signing state and block recovery of valid shares from other peers.
Code changes brief
ProcessPendingSigShares()and skip processing their whole collected batch after verification.CConnman, including peers already marked for disconnect, so late messages remain ignored until the peer is fully removed.cmake --build build -j$(nproc)andctest --test-dir build --output-on-failurepassed (104/104).
