FN-6735: treat benign merge-seam pause aborts as retryable
Treat benign pause/resume aborts at workflow merge seams as retryable transient merge failures.
- Classify legacy, merge-region, manual-hold, and retry node ids as merge-seam graph failures.
- Route clean in-review pause/resume aborts back through bounded auto-merge retry when eligible.
- Keep conflict, contamination, foreign-work, exhausted-retry, global/user pause, and confirmed-merge cases terminal.
- Cover the lifecycle with a reliability regression test and architecture notes.
