fix: FleetReview #1371 P1s -- newly-skipped job blocks full re-run; atomic capture-router staging (t_06bf7c49)

[ang-fleet-workers]

Kanban t_06bf7c49. Two FleetReview P1 findings on #1371 @430c5ba9, both real-open on main 667885f.

1. scripts/ci_overflow_integration.py (fb763f44): full_rerun_verdict let a job that ran in attempt N but was skipped (started_at null) in N+1 through: not reused, not missing_probe, not absent -> PASS. Now BLOCK with evidence.newly_skipped; skipped-in-both stays exempt.
2. plugins/memory/mem0/capture_router.py (d82676bc): route_turn treats an existing <turn_id>.md as a completed stage, but _default_write wrote in place. Now tmp (non-.md name) + fsync + os.replace.

Tests: one regression test each; both fail on main, pass here. 41 passed across tests/test_ci_overflow_integration.py and tests/plugins/memory/test_mem0_capture_router_retry.py.
