ci(workflow): fetch tiny stories15M GGUF via git-lfs before configure; run unit+integration tests

- Use git-lfs to download stories15M-q4_0.gguf from ggml-org/models
- Download model before CMake configure so if(EXISTS ...) condition works
- Update all config files and tests to use consistent model path
- Run comprehensive YAML config test suite in CI
