Add a table

Work through every step; a table without ACLs, tests or registration is not done. Check property names with npx now-sdk explain table --format=raw (and acl, restapi, test) rather than guessing.

Names below use widget as the example entity; keep the project's scope prefix (x_snc_example unless npm run setup changed it — read scope from now.config.json).

1. Table — create src/fluent/tables/widget.now.ts:
   • export const x_snc_example_widget = Table({ name: 'x_snc_example_widget', label, display, schema: { … } })
   • every column name starts with x_snc_example_; pick column types from npx now-sdk explain --list (*column-api)
   • allowWebServiceAccess: true only if the REST Table API must reach it
   • actions: { read: true } (object form; controls cross-scope access — add writes only if another scope needs them)
2. ACLs — in src/fluent/acls/, one Acl() per operation (read, create, write, delete), type: 'record', table: 'x_snc_example_widget', roles: [exampleUserRole] or [exampleAdminRole] imported from ../roles/app-roles.now.
3. Service — add methods to src/server/AppService.server.js (or a new Script Include, see AGENTS.md). Use GlideRecordSecure, validate input, return { status, body } like the existing item methods. Any platform API the template does not already call needs a CrossScopePrivilege (runtime access is enforcing; see AGENTS.md).
4. REST routes — add routes to src/fluent/rest-api/app-api.now.ts (/widgets, /widgets/{sys_id}), each with its own $id and enforceAcl: [exampleApiAcl]; scripts only call the service and svc.send(response, result).
5. ATF test — add a Test() to src/fluent/tests/ that inserts a record, validates it, exercises the service methods via runServerSideScript (use assertEqual), and add it to the TestSuite. Every step gets a unique $id.
6. Register — export * from './tables/widget.now' in src/fluent/index.now.ts (other files import by side effect).
7. Verify — npm run lint && npm run build; commit the src/fluent/generated/keys.ts changes with the code. If an instance is available, run the deploy-and-verify skill.
8. Docs — add the table to the "What gets deployed" table in README.md and a line under [Unreleased] in CHANGELOG.md.
