## Summary
- Wire up the existing `document_format` feature to LSP via stateless
workers
- Add `Format` kind to stateless worker dispatch, with a lightweight
`forward_format` path in `Compiler` (no compilation/deps needed — just
file path + content)
- Register `textDocument/formatting` and `textDocument/rangeFormatting`
handlers with `scoped_pause`
- Style lookup uses `clang::format::getStyle` which walks parent
directories for `.clang-format`, matching clangd's behavior
## Test plan
- [x] 4 unit tests: simple format, range format, idempotent (no edits),
include sort
- [x] 3 integration tests: full document format (verifies applied edits
match expected output), range format, already-formatted no-op
- [x] Capability assertions added to `test_capabilities`
- [x] All existing tests pass (554 unit, 170 integration, 2 smoke)

## Summary by CodeRabbit
* **Tests**
* Reorganized integration suites: added new feature tests (completion,
server) and removed older duplicated modules.
* Centralized shared test utilities and assertion helpers for
diagnostics, workspace operations, waiting/synchronization, and cache
inspection.
* **Chores / Refactor**
* Standardized test client lifecycle and helper usage across suites for
more reliable test flows.
* Improved server session lifecycle handling for more predictable
document/session resets during tests.
