- BIFROST_DB_PATH env var overrides the default bifrost.db path; lets
vitest open ':memory:' per suite without touching prod data.
- Extend User/UserPublic with title, cab_joined_date, slug.
- Update SELECT lists for getUserPublicById and getAllUsersPublic.
- Add getUserBySlug for /members/:slug routes.
- Add slugifyName + generateUniqueSlug; createUser now auto-slugs from name
and stamps cab_joined_date for cab-role users.
