The curated `image_exif` columns are a small slice of what exiftool
can read (camera/lens/GPS/capture/dates). Apollo's DETAILS modal wants
to surface everything — white balance, metering, MakerNotes, IPTC,
ICC profile, Composite tags, the lot — for an operator inspecting a
photo's provenance.
`read_full_exif_via_exiftool(path)` shells out to `exiftool -j -G -n`:
JSON output, group-prefixed keys (`EXIF:Make`, `MakerNotes:LensInfo`),
numeric values (callers can reformat). Spawned via web::block to keep
it off the actix worker — RAW with rich MakerNotes can take a few
seconds.
The endpoint is on-demand only; the indexer / file watcher does NOT
call it. Falls back to 503 with a clear message when exiftool isn't
on PATH so Apollo can render an "install exiftool" hint. Multi-library
union resolution mirrors set_image_gps / get_file_metadata.

Pass -P to exiftool so write_gps doesn't bump the file's modification
time. For phone photos with no embedded EXIF datetime, the filesystem
mtime is often the only timestamp we have — losing it on every GPS
backfill would be data loss.

New endpoint accepts {path, library, latitude, longitude} and shells
out to exiftool to write GPSLatitude/GPSLongitude (with N/S, E/W refs)
into the file's EXIF in place. After the write, the handler
re-extracts EXIF and updates the image_exif row so the DB stays in
sync — the response carries the updated metadata block in one
round-trip. Falls through to store_exif if the row is missing.
`exif::write_gps` is the small helper. `-overwrite_original` so no
.orig sidecar is left behind. Validates lat/lon range + supports_exif
before spawning exiftool. Format support matches the existing read
path (JPEG / TIFF / RAW / HEIF / PNG / WebP) — videos still need a
different writer and aren't covered.
Apollo's "+ PIN" carousel button (separate commit on the Apollo side)
calls this through /api/photos/exif/gps. Drive-by: cargo fmt one-line
collapse on apollo_client.rs.

kamadak-exif's In::PRIMARY / In::THUMBNAIL only address IFD0 and IFD1.
On modern Nikon NEFs the full-res review JPEG lives in the MakerNote's
PreviewIFD (and many Canon CR2s / DNGs put theirs in a SubIFD chain) —
both unreachable through the existing reader, so the previous patch
still produced no preview for those files and the pipeline fell through
to ffmpeg, which writes black frames when it can't decode the RAW.
Add a slow-path layer in extract_embedded_jpeg_preview that shells out
to exiftool for PreviewImage / JpgFromRaw / OtherImage (one process per
tag). All candidates from both layers are pooled and the largest valid
JPEG wins. exiftool not on PATH degrades to fast-path-only behavior
rather than breaking — the fallback is a strict superset.
Documented the new optional dependency in README.md and CLAUDE.md with
install commands for apt / brew / winget / choco.

The thumbnail pipeline's embedded-JPEG extractor only checked IFD1
(THUMBNAIL), which on many Nikon NEFs is missing or zero-length even
when IFD0 (PRIMARY) carries a perfectly good 1-2 MP reduced-resolution
preview the camera writes for in-body review. The previous behavior
produced black thumbs on disk: the buggy IFD1 pointer resolved to a
short byte sequence that happened to satisfy the SOI sanity check,
image::load_from_memory accepted it, and the resize path quietly wrote
a black JPEG.
Now both IFDs are checked and the larger valid JPEG wins. Format-
agnostic: applies to every TIFF-based RAW (NEF / ARW / CR2 / DNG / RAF /
ORF / RW2 / PEF / SRW / TIFF). is_tiff_raw is now pub so main.rs can
gate its full-size handler on it.
Also extends the /image handler so size=full requests for RAW formats
serve the embedded preview as image/jpeg instead of NamedFile-streaming
the original RAW bytes - browsers can't decode a .nef container, so
<img src=...> would otherwise land as a broken image. Falls through to
NamedFile if no preview is present, preserving the historical behavior
for callers that genuinely want the original bytes.

Two follow-ups on the same feature branch:
1. Bake EXIF orientation into generated thumbnails. The `image` crate
doesn't apply Orientation on load, and `save_with_format(..Jpeg)`
drops EXIF — so portrait phone shots ended up sideways in any client
that displays the cached thumb directly (no EXIF tag for the browser
to compensate from). New `exif::read_orientation` reads the tag
cheaply (no full EXIF parse) and `exif::apply_orientation` does the
rotate/flip via image's existing `rotate90/180/270` + `fliph/flipv`.
Applied in both branches of `generate_image_thumbnail` (RAW embedded-
JPEG path and the regular `image::open` path). Existing thumbnails
in the cache are still wrong-orientation; wipe the thumb dir or run
a one-off backfill once this lands.
2. Optional `library` query param on `/photos/exif`. Accepts numeric id
or name (same shape as `/image?library=...`), resolved via the
existing `resolve_library_param` helper so a bad value 400s before
we touch the DAO. Filter is applied post-query in the handler
rather than pushed into `query_by_exif` to keep the DAO trait
(and its test mocks) unchanged. Cheap enough at typical library
counts; can be moved into SQL later if it ever isn't.

Three recurring issues on every full scan:
1. Video playlist scans re-enqueued every file only to reject it as
AlreadyExists. Pre-filter in ScanDirectoryMessage and QueueVideosMessage
so we skip videos whose .m3u8 already exists, and demote the leaked
AlreadyExists log to debug.
2. image crate was built with only jpeg/png features, so webp/tiff/avif
files logged "format not supported" every scan. Enable those features.
3. RAW (ARW/NEF/CR2/...) and HEIC thumbnails weren't generated, so the
scan kept retrying them. Try the file's embedded JPEG preview via
kamadak-exif first (fast, pure-Rust, works on Sony ARW where ffmpeg's
TIFF decoder fails). Fall back to ffmpeg for HEIC/HEIF and RAWs with
no preview. Anything still undecodable gets a <thumb>.unsupported
sentinel so future scans skip it.
