jif-oai 0e821b380a rollout: coalesce thread updated_at touches (#21367) ...

## Why

Metadata-irrelevant rollout events currently refresh
`threads.updated_at` on every flush. That keeps thread recency accurate,
but it also turns high-frequency agent output into unnecessary SQLite
writes. Recency only needs to advance periodically during an active
session, while the final suppressed touch still needs to be persisted
before shutdown.

## What changed

- coalesce touch-only `updated_at` writes in the rollout writer, with a
short production interval between persisted touches
- retain the latest suppressed touch and flush it during shutdown so the
thread is not left stale
- extend rollout recorder coverage for coalesced touches, delayed
refresh, shutdown flushing, and the existing missing-thread fallback
path

## Verification

- Added regression coverage in `rollout/src/recorder_tests.rs` for
coalescing and shutdown flushing behavior.
