- Rewrite db.php to use SQLite via PDO (no external DB server needed) - Rewrite schema.sql for SQLite (AUTOINCREMENT, CHECK constraints, triggers for updated_at, ON CONFLICT instead of ON DUPLICATE KEY) - Fix config.php upsert to use ON CONFLICT syntax - Fix index.php: tag filter via json_each, vote upsert via ON CONFLICT, and fix protocol create route (was returning 405 for POST /api/protocols) - Fix yaml.php seed import: replace invalid false callbacks with fn() => null, fix yaml_parse pos argument (-1 -> 0) - Update Dockerfile: drop pdo_mysql/mysqli (pdo_sqlite is built in) - Update CloudronManifest.json: remove mysql addon, bump to v0.3.0 - Update README for SQLite deployment
