v0.26.0 — looks-like preview, debounced cue refresh

on GitHub

• Looks-like cues show the gallery face. Unknown review now stores guess_top_slug +
  guess_top_photo (the reference that best explains a guess) and shows a thumbnail next to
  looks like / ★ Looks like headers; hover enlarges, click opens the existing full viewer.
  Keys are omitted when there is no photo; deleting or setting aside a reference photo
  refreshes dangling cues. Contributed by @Alien10140.
• Cue refreshes no longer run once per request. Deleting, setting aside, restoring and
  deduplicating photos each used to re-match every unknown on the HTTP thread. They now
  schedule one debounced background pass instead, so a cleanup burst costs a single pass. The
  visible difference: cues update a moment later rather than instantly, and at most
  max_delay (2 s) after the first request in a burst, so a long stream of deletions cannot
  defer them indefinitely. Assign, unassign and ignore still refresh immediately, because
  those are the actions where the review list must be right the moment it reloads.
• The unknown metadata is written safely. Each file is written to a unique temporary name
  and moved into place, with flush + fsync before the move and the directory synced once
  per pass — a half-written file can no longer become the real one, and a power cut cannot
  leave a zero-length file where an embedding was. The pass runs under its own lock, the
  file's permissions are preserved, and an unknown that was assigned or discarded mid-pass is
  no longer recreated as an entry without an image.
