b2207c3357 Persist notification images so history keeps avatars (#6804 )

* Persist notification images so history keeps avatars

Persisted popup and history entries stored image/appIcon as URLs into
resources that die with the live notification: Chromium-family senders
(every Omarchy web app, WhatsApp included) pass avatars as files in a
scoped /tmp dir deleted when the notification closes, and raw image-data
hints surface as in-process image:// URLs that die with the server
object. Replaying history then found dead references and hid the icon.

Copy file-backed images into the notification state dir when persisting,
keyed by the entry's file stem, and reference the copies from the JSON.
Blank dead image:// URLs so the card falls back to the app icon. The
copies die with their JSON: superseded-popup deletes, history trims and
clears remove them, and a startup sweep collects copies orphaned by a
restart killing a queued job mid-write.

Hold DND-silenced notifications open until their history write has run,
since untracking tells the sender to delete its avatar file, and carry
replayed on-screen rows over via their persisted copies, since the
replay dismisses their live notifications first.

* Coalesce silenced updates and bound image copies through temp files

A replaces_id update lands on a held DND notification without a second
onNotification, so releasing after the first write could persist a stale
snapshot. Re-snapshot when the write completes and write again until the
content is stable, reusing the original file identity.

The image copy reopened the sender-controlled path after checking it, so
a file growing or becoming a FIFO mid-copy defeated the size bound. Read
through head -c under a timeout into a temp file, validate its size, and
rename it into place; the startup sweep clears temp files a killed job
leaves behind.
