Brandon ThomasandClaude Opus 5.5 771b0b98d7 Issue #106: Convert to DNG and smart previews: verified, atomic writes
- Convert to DNG / Copy as DNG: the encoded DNG must decode to the same raw
  data, then goes through safe_file::write_new_unique (temp file, sync,
  read-back, hard-linked to the first free <stem>.dng / -2 / -3 name, never
  replacing a file). On failure no DNG is left, the photo is not relinked
  and the raw copy is kept.
- Photo Merge writes its DNG the same way.
- Smart previews are written atomically; smart::is_valid (header + complete
  JPEG) decides "built", has_smart_preview and the offline fallback, so a
  proxy cut short is rebuilt (reported as `repaired`); moving proxies to a
  new folder never deletes a good one in favour of a damaged copy and
  copies across drives atomically.

Stacked on the #93 branch (shared lightcraft_catalog::safe_file helper).
