fix: address PR review — lint, dedup scope, and cleanup targeting

- Remove unused `autoCleanCorrupted` param from decryptMessageNode (lint fix)
- Scope retry dedup by participant JID in group chats (not group JID)
- Move dedup registration after early-return checks to avoid blocking
  subsequent messages when max retries reached
- Use participant JID for session cleanup in groups (Signal sessions
  are per-participant, not per-group)
