Resolved against rb-base-36: Scanned keeps the base's rewrite flag next to magic and tag; Exif keeps the Panasonic lens fallback; locale catalogs merged (one duplicate key dropped).

Photos imported before focus points were read got one only through Reload from Disk, which
hashes whole files on the UI thread. Now:
- lightcraft_meta::focus::read_header reads only what the decoder looks at: IFD0 (Make,
Model), the Exif IFD, the maker note's IFD and the focus tags' values (a JPEG: its segments
up to the Exif one), walked round by round and decoded with the whole-file code from a
buffer of the file's length holding just those ranges. Bounded rounds, bytes (2 MB) and
size (1 GB). One 32 KB read per α1 / A7S III ARW; on 109 real files (83 with a point)
it gives the whole-file read's point for every one.
- A background job (crates/engine/src/focus_scan.rs) reads photos with no point from a
supported body (by the stored camera; nothing else is opened), ARW or JPEG, one at a
time in path order, with a "Reading focus points" activity row (Cancel::Flag). The UI's
per-frame focus.pump gives it the face scan's pace (paused while dragging or typing) and
starts it once per library opening. Commits every 200 photos or 3 s as system ops (no
undo step, no sidecar write), only meta.focus, only on photos that still have none at the
same path. "Looked, none" goes to focus-scanned.bin beside the library, headed by the
decoder's tag so a decoder knowing more bodies starts afresh; unreadable files are retried
at the next opening.
- photo.readFocusPoints {ids?, wait?} (Photo > Read Focus Points) runs it on demand.
Measured cold on a 5400 rpm USB drive: 200 α1 / A7S III ARWs in 1.9 s (~100 photos/s,
32 KB each), so 58,796 raws take about 10 minutes instead of re-reading 2.25 TB.
While photos are left to search for faces the stack shows "Finding
faces" with how many are done (no cross: the scan is switched off in
Settings). The engine keeps the scan's peak, so Settings and the stack
agree. Also translates the "Downloading model" label.

Keep current upstream UI behavior and the later detector contract checks. Validate candidate models before replacing working weights and records, with a synthetic regression that failed before the fix. Remove the unrelated GPU equivalence-test relaxation. All seven quality gates pass with the pinned hosted fonts.
