TypeScript/Bun project scaffold

- Stack: Bun, Hono, Drizzle ORM, Zod, Handlebars, Pino
- Models: ticket, queue, transaction, scrip, template, custom_field, user, lifecycle
- Scrip engine: prepare/commit two-phase dispatch, template rendering, mock actions
- Lifecycle validator: state machine transition validation with wildcard support
- Routes: health, tickets (full CRUD + preview + transactions), queues, scrips, custom-fields, lifecycles
- Middleware: Pino logging, error handler
- Database: Drizzle ORM schema + initial migration (10 tables)
- Type-check: passes (tsc --noEmit, zero errors)
