Subject: [PATCH 4/8] eval retry: keep both attempts in latency + cost, gate
 retained-sample routes, survive a failed rerun

- latencySamplesForRetry retains every retried case's first attempt (latency and cost), not only latency-gate ones
- route p95 buckets built from final results and retained samples
- a rerun that throws keeps the first-attempt report and records retry_error
- retry markdown describes the both-samples latency population
- test: final verdict built with the retained sample; new moved-route test
- prettier on changed files (fixes Changed-file format check)

Subject: [PATCH 8/8] test(roster): pin the clock in the give-away test so it
 stops expiring

The give-away sheet reads the real clock, and the fixture shift (Thu 15 Oct,
09:00 Perth) counts as urgent inside 24 hours, which swaps "Offer to 1 person"
for "I can't make it". The test passed only while the real date was more than a
day before the shift. From 09:00 Perth on 14 Oct 2026 it failed on every run,
turning Unit coverage red on main and on every PR. Date is now pinned to two
days before the shift for that one test.
