Pull request overview
This PR tightens consensus behavior and sync heuristics by adding an extra guard when a competing proof exists, and by adjusting nonce sequence detection logic to be nonce-ordered rather than arrival-ordered. It also introduces/validates a new process config knob used by the sync logic and updates test defaults accordingly.
Changes:
- Drop received signature shares during EndRound when a competing block proof is detected.
- Sort the “recent desynced nonces” sample before checking consecutivity to better handle out-of-order proof arrivals.
- Add
RoundModulusTriggerWhenSyncIsStuckdefaults + validation, and extend unit tests to cover the new validation.

|---|---|
| testscommon/components/configs.go | Adds the new round-level process config default used in tests/common setups. |
| consensus/spos/bls/v2/subroundEndRound.go | Drops signatures early when a competing proof is present. |
| consensus/spos/bls/ntpsync/roundSyncController.go | Sorts nonce samples before consecutivity check to make resync trigger independent of arrival order. |
| common/configs/processConfigs.go | Validates RoundModulusTriggerWhenSyncIsStuck is non-zero to prevent modulo-by-zero. |
| common/configs/processConfigs_test.go | Updates configs used in tests and adds a test for the new validation. |
