Ruff lint surfaced 23 violations across three rules; all addressed:
UP017 (Use datetime.UTC alias):
Replaced 13 sites of datetime.now(timezone.utc) with datetime.now(UTC),
also adjusted from-imports accordingly. UTC is a Python 3.11+ alias for
timezone.utc that ruff's pyupgrade rules prefer.
UP042 (StrEnum):
Replaced `class TagKind(str, Enum)` and `class SkipReason(str, Enum)`
with `class Foo(StrEnum)`. StrEnum was added in Python 3.11 stdlib and
is the modern idiom. Behavior is equivalent for our usage (the .value
attribute, str(member) semantics).
I001 (Import sorting):
Added `known-first-party = ["backend"]` to ruff.toml's [lint.isort] so
ruff groups `backend.*` imports correctly. Without it, ruff treated
them as third-party and demanded a different grouping. The existing
import order is stdlib → third-party → first-party → local relative,
which ruff now accepts.

Single-file pipeline: validate as image, apply filter rules (min dimensions,
transparency), SHA256 hash dedup, atomic copy to /images/{subdir}/, create
ImageRecord with origin='imported_filesystem' and integrity_status='unknown',
auto-derive top-level folder name as Artist + artist tag.
Importer is intentionally sync (consumed by a Celery worker process); the
async Quart side uses the same ORM through its own async session. The
db_sync fixture in conftest.py was added in Task 3 to support these tests.
Thumbnail generation is NOT inlined; the calling Celery task enqueues a
separate thumbnail task so the import queue keeps moving on big batches.
pHash dedup is FC-2d, not here.
