Deployed databases can persist without the revision_history table,
causing /play/<token>/revise to crash with sqlite3.OperationalError.
- log_revision() now creates the table on the fly if it is missing.
- app.py runs init_db() at import time (safe CREATE TABLE IF NOT EXISTS)
so new deployments auto-create missing tables on startup.
Bump patch version 0.4.0 -> 0.4.1.
When a request has revision_note set, the operator now sees a
'Copy revision prompt for Hermes' button in the revision note box.
It copies a prompt that includes:
- the original customer brief,
- the previously generated title/style/lyrics,
- the customer's revision request,
- the signed callback URL and expected JSON shape.
Minor version bump: 0.3.0 → 0.4.0.
- New VERSION file at project root, starting at 0.3.0.
- config.py reads VERSION and exposes it as Config.VERSION.
- Admin settings page now renders the live version from config.
- Semantic versioning convention: MAJOR for breaking/user-facing changes,
MINOR for new features, PATCH for bug fixes and small polish.
