Subject: [PATCH 01/12] feat(common): Add YAML config loader with yaml-cpp
 dependency

- Add common/config.h and common/config.cpp for YAML configuration loading
- Implement common_load_yaml_config() with validation and path resolution
- Add yaml-cpp dependency via FetchContent in common/CMakeLists.txt
- Support nested config structure (model, sampling, speculative, vocoder)
- Reject unknown keys with descriptive error messages
- Resolve relative paths relative to YAML file directory

Subject: [PATCH 02/12] feat(arg): Add --config flag with YAML pre-scan and
 precedence logic

- Add --config flag to argument parser with pre-scan before flag parsing
- Implement YAML loading before common_params_parse_ex to ensure proper precedence
- Flags override YAML values, YAML overrides defaults
- Add --config option to usage help and argument definitions

Subject: [PATCH 03/12] test: Add unit tests and CTest integration tests for
 YAML config

- Add test-config-yaml.cpp with unit tests for config parsing and error cases
- Add three CTest integration tests: yaml-only, yaml-plus-overrides, parity
- Add test-yaml-parity.sh script for comparing YAML vs flags output
- Gate integration tests on model file existence to avoid CI failures
- Use absolute paths in parity test to handle CTest working directory

+### YAML Configuration
+
+You can use YAML configuration files to set parameters instead of command-line flags:
+
+```bash
+llama-cli --config configs/minimal.yaml
+```
+
+Example `minimal.yaml`:
+```yaml
+model:
+  path: models/tinyllama-1.1b-chat-v1.0.Q4_K_M.gguf
+n_ctx: 256
+sampling:
+  seed: 42
+  temp: 0.0
+prompt: "Hello from YAML"
+n_predict: 16
+simple_io: true
+```
+
+You can override YAML values with command-line flags:
+```bash
+llama-cli --config configs/minimal.yaml -n 32 --temp 0.8
+```
+
+**Precedence rules:** Command-line flags > YAML config > defaults
+
+**Path resolution:** Relative paths in YAML files are resolved relative to the YAML file's directory.
+
+**Error handling:** Unknown YAML keys will cause an error with a list of valid keys.

Subject: [PATCH 07/12] ci: fix CURL dependency and editorconfig violations

- Add -DLLAMA_CURL=OFF to test-yaml-config workflow
- Remove trailing whitespace from workflow, config.cpp, arg.cpp
- Add yaml-cpp build flags to disable tests/tools/contrib
- Fix spacing consistency in config.cpp

Subject: [PATCH 08/12] fix(ci): use existing tinyllama model and scope
 yaml-cpp to tools

- Update CI workflow to use existing tinyllama-1.1b-chat-v1.0.Q4_K_M.gguf model
- Update all config files and tests to reference the existing model
- Scope yaml-cpp dependency to LLAMA_BUILD_TOOLS only with compile guards
- Suppress all warnings for yaml-cpp to avoid -Werror failures
- This resolves the 404 model download and cross-platform build issues

Subject: [PATCH 10/12] 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

- Replace git-lfs clone of entire ggml-org/models repo (10.91 GiB)
- Use direct wget download of stories15M-q4_0.gguf (19MB only)
- Prevents 'No space left on device' errors in GitHub Actions

Subject: [PATCH 12/12] cmake(common): scope config.cpp/yaml-cpp to tools; add
 LLAMA_ENABLE_CONFIG_YAML guards

- Wrap --config option definition with LLAMA_ENABLE_CONFIG_YAML in arg.cpp
- Guard all YAML-dependent code sections in config.cpp and config.h
- Ensures yaml-cpp is only compiled when LLAMA_BUILD_TOOLS=ON
- Prevents platform builds that don't need tools from pulling yaml-cpp dependencies
