dtoro 574d71371f refactor: strip AI pipeline to binary photo/other classifier
Drops face recognition, OCR, object detection, and semantic embeddings.
The sole remaining vision task is a CLIP-based binary classifier
(photography vs other); photos in "other" get needs_review=true so
screenshots, documents, memes and scans can be triaged from a new
filter pill in the UI.

"""
Alembic environment for PhotoVault.
Pulls DATABASE_URL from the environment so the same migrations work in
docker compose and locally. Strips the async driver suffix because Alembic
runs synchronously via psycopg2.
Future-migration note
---------------------
Fresh installs run `Base.metadata.create_all` in `app.database.init_db`
*before* migrations would normally apply, so any migration that adds a
column / index / table to an object the model already declares will see
that object already present. Write migrations defensively:
op.execute("ALTER TABLE photos ADD COLUMN IF NOT EXISTS new_col TEXT")
op.execute("CREATE INDEX IF NOT EXISTS ix_foo ON foo(bar)")
For brand-new tables that the model also declares, the same applies — use
`op.execute("CREATE TABLE IF NOT EXISTS ...")` or check first.
