refactor(codegen): remove deprecations, unify camelizeArgv, clean up redundant wrappers

- Undeprecate generators/index.ts (active v5 code, not legacy v4)
- Undeprecate MetaObject/QueryBuilder exports in core/index.ts
- Remove deprecated formatOutput() and its test (replaced by writeGeneratedFiles)
- Remove buildSchemaSDLFromDatabase() wrapper, callers use buildSchemaSDL directly
- Unify camelizeArgv: camelize once at top of each CLI handler, remove dual manual-kebab + later-camelize pattern
