- **fixed** — the selector-form keyPrefix overload of getFixedT() is now available under enableSelector: 'strict'

- fix(types): the selector-form `keyPrefix` overload of `getFixedT()` is now available under `enableSelector: 'strict'`. Its constraint was gated on `true | 'optimize'` only, so under `'strict'` it collapsed to `never`, the overload dropped out, and the returned `t` silently lost its `keyPrefix` scope (`t(($) => $.deep)` failed with `Property 'deep' does not exist on type '{}'`). The same call already typechecked under `true` and `'optimize'`. Thanks @hovelopin ([#2446](https://github.com/i18next/i18next/pull/2446)).
