The llama.cpp b11077 release addresses a bug in router mode where the `--api-key-file` argument was incorrectly forwarded to router-spawned child instances. This caused clients using `--api-key` to receive 401 errors on chat completions and prevented internal router stream calls from working.
- Unsets `LLAMA_ARG_API_KEY_FILE` in `unset_reserved_args()` so no API keys reach child instances.
- Ensures all keys the router accepts work end-to-end without re-validation against file keys.
- Prevents router internal stream calls, such as POST /v1/streams/lookup and DELETE /v1/stream, from being silently rejected with 401 errors.
This fix resolves issue #28820 by ensuring authentication remains the responsibility of the router rather than child processes.
