Introspects the merged authz catalog, emits app/authz/permissions.gen.ts
type unions, and scaffolds the assignment-table migration. init validates
--dialect explicitly (unrecognised values reject rather than silently
falling back to sqlite) and joins authzMigrationSql's up/down statement
lists with terminators instead of interpolating the arrays.
Test scaffolding for dynamically-imported app/authz declarations must
live inside the repo tree (not os.tmpdir()) for the "@wrnexus/*" bare
specifier to resolve via tsconfig paths; .gitignore excludes the scratch
dirs this produces.
