refactor(cli): hoist gen name validators to module constants

The name-validation regexes in the gen arg parsers were inline literals,
recreating a RegExp on every parser call and duplicating two identical
patterns across five sites. Hoist them to two module-level constants
(NAME_RE for model/migration, NAME_WITH_HYPHENS_RE for middleware/cron/
queue). Behavior is unchanged (anchored, non-global validators).
