feat(tag-kinds): drop meta + rating entirely — alembic 0023 deletes existing meta/rating tags (CASCADE clears related image_tag / alias / allowlist / suggestion_rejection / reference_embedding / series_page rows) then recreates the tag_kind ENUM without those values. Python TagKind enum trimmed; KIND_OPTIONS + KIND_COLOR + KIND_ICONS maps + TagsView KINDS array all updated. Operator confirmed they have no use for the data.

+"""drop meta + rating tag kinds — operator-retired 2026-05-26
+
+Revision ID: 0023
+Revises: 0022
+Create Date: 2026-05-26
+
+Operator decided meta + rating aren't valid tag kinds for FC. Per-row
+behavior: DELETE existing rows (operator chose "clean break" over
+"convert to general"). All cascading FKs (image_tag, tag_alias,
+tag_allowlist, tag_reference_embedding, tag_suggestion_rejection,
+series_page) use ondelete="CASCADE" so a single DELETE on tag cleans
+the related rows in one go.
+
+After the data cleanup, recreate the tag_kind ENUM without 'meta' /
+'rating' (Postgres has no `ALTER TYPE ... DROP VALUE`; standard
+rename-create-cast-drop dance). The server default 'general' is
+dropped before the type swap and restored after.
