- Rename `getModuleMetadata` to `getModuleMetadataGenerator` in registry,
index, and client exports to clarify its purpose (returns a generator
function, not a metadata object)
- Add new `getModuleMetadata` and `getMetadataGenerator` exports from
`modules.metadata.js` for server-side metadata object retrieval
- Update route auth format in docs from `requireAuth`/`requireAdmin`
flags to a single `auth` field with values: `'admin'`, `'user'`,
or `'public'`
- Fix `isModuleEnabledInEnv` to replace hyphens with underscores in
env var names (e.g. `my-module` → `ZEN_MODULE_MY_MODULE`)
- Replace `useState` initializer in `ZenProvider` with `useRef` guard
to avoid React strict mode double-invocation issues
