## Summary
- **`[[rules]]`**: TOML array-of-tables config for per-file compilation
flag rules with glob pattern matching (`append`/`remove`). Patterns are
pre-compiled at config load time. Rules whose patterns all fail to
compile are dropped entirely (no silent no-op entries), and rules now
apply uniformly to every compilation — including the header-context
fallback path used when editing a header without its own CDB entry.
- **CDB auto-scan**: Default search scans workspace root + all immediate
subdirectories for `compile_commands.json`, replacing the hardcoded
directory list.
- **LSP `initializationOptions`**: Clients can pass config as JSON via
the LSP initialize request; priority is `initializationOptions >
clice.toml > defaults`.
- **XDG cache paths**: Default cache/index/logging paths prefer
`$XDG_CACHE_HOME/clice/<workspace-hash>/`; fall back to
`$HOME/.cache/clice/<hash>/`, then `<workspace>/.clice/`.
- **`${workspace}` substitution**: supported in `cache_dir`,
`index_dir`, `logging_dir`, and every `compile_commands_paths` entry.
No-op when `workspace_root` is empty.
- **Partial config support**: All TOML/JSON fields are optional via
`kota::meta::defaulted<T>`, so minimal config files work correctly.
- **Detailed diagnostics**: malformed `clice.toml` now logs line, column
and parser description (via toml++ direct parse); a malformed workspace
config surfaces a clear fallback warning instead of silently reverting
to defaults.
## Test plan
- [x] 28 unit tests for config (full suite 545 unit tests pass, Debug)
- [x] 119 integration tests pass
- [x] 2 smoke tests pass

## Summary by CodeRabbit
* **New Features**
* XDG-based, workspace-scoped project cache (PCH/PCM and header caches
moved under project cache) with workspace fallback
* Initialization options JSON can override config (takes precedence over
file/defaults)
* Per-file pattern rules to append/remove compile flags; expanded
discovery of compilation databases (multiple paths)
* **Refactor**
* Configuration fields reorganized under a project scope; runtime
behavior now respects project-scoped values
* **Tests**
* New unit and integration tests for config parsing, rule matching, and
persistent cache behavior

## Summary
- **CMake-based CDB generation for module tests**: Replace hand-written
compile_commands.json with CMakeLists.txt (CMake 3.28 `FILE_SET
CXX_MODULES`) in all 26 `tests/data/modules/*/` directories. CDB is
generated on-the-fly via `cmake -G Ninja` during test setup.
- **`@pytest.mark.workspace()` decorator**: Introduce a marker + fixture
pattern so tests declare their workspace via decorator and receive a
resolved `workspace` path. The fixture auto-generates CDB when a
CMakeLists.txt is present.
- **`CliceClient` helper methods**: Add `initialize()`, `open()`,
`wait_diagnostics()`, and `open_and_wait()` to reduce boilerplate across
all test files.
- **Use `asyncio_mode = "auto"`**: Switch from `@pytest_asyncio.fixture`
+ `@pytest.mark.asyncio` to `@pytest.fixture` + auto mode for proper
Pylance type inference on fixtures.
- **Test cleanup**: Remove redundant section separators and docstrings,
delete `tests/pyproject.toml` (config moved to `pytest.ini`).
- **Format task**: Add `.cppm` to `format-cpp` glob pattern.
- **CI fix**: Disable `CMAKE_CXX_SCAN_FOR_MODULES` and prefer pixi
clang++ to fix macOS CI where CMake rejects module scanning.
## Test plan
- [x] All 26 module test directories have CMakeLists.txt with FILE_SET
CXX_MODULES
- [x] generate_cdb() produces valid compile_commands.json with module
flags
- [x] Integration tests pass locally
- [ ] CI passes on all platforms (Linux, macOS, Windows)

## Summary by CodeRabbit
* **Tests**
* Unified fixtures and client workflow: new init/open/wait helpers,
workspace marker support, bounded diagnostics waiting, CMake-based
compilation-database generation, and directory-backed temp-file
workflows; enabled asyncio test mode.
* **Chores**
* Added many C++20 module test projects and test data; removed prior
test pyproject in favor of pytest config; updated formatter to include
.cppm files.
* **Style**
* Reformatted many module/source implementations to consistent
multi-line function bodies.
