Refactored `_check_dedup` to collect superseded observation IDs and update them in a single database call using `ANY($1::uuid[])`. This eliminates the N+1 query issue where multiple sequential `UPDATE` statements were executed within a loop. The optimization reduces database round-trips from up to 5 to exactly 1 (or 0 if no contradictions are found), improving efficiency in the deduplication pipeline. Verified with a mock-based test script covering full loop completion and early return branches. Full project tests were attempted but blocked by missing environment dependencies.

💡 What: Batched database updates for superseded observations in the
_check_dedupfunction.🎯 Why: To solve an N+1 query inefficiency where each superseded observation triggered a separate
UPDATEstatement within a loop.📊 Measured Improvement: Reduced database round-trips from O(N) to O(1) for the supersede logic. Although direct latency measurements were impractical due to environmental constraints (missing dependencies and no internet), this change theoretically reduces database contention and network overhead by consolidating multiple updates into a single batched query using PostgreSQL's
ANY($1::uuid[])syntax. logic ensures all identified contradictions are flushed before any early returns (e.g., when a duplicate is found), preserving original behavior with better efficiency.PR created automatically by Jules for task 4552571063671409468 started by @LeandroPG19
