## 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
- **Restructure `src/server/` into subdirectories** (`service/`,
`compiler/`, `worker/`, `workspace/`, `protocol/`) to separate concerns:
transport/session management, compilation, worker orchestration, and
persistent workspace state.
- **Decouple MasterServer from transport**: MasterServer no longer holds
a `JsonPeer&` reference or registers handlers itself. New `LSPClient`
and `AgentClient` classes own their peer references and register
protocol handlers, accessing MasterServer internals via `friend class`.
- **Add agentic protocol**: A TCP-based side channel
(`agentic/compileCommand`) that lets external tools (AI agents, build
systems) query compile commands from a running clice server. Includes a
CLI client mode (`--mode agentic --port N --path FILE`), server-side
listener when `--port` is specified in pipe mode, and integration tests
for happy path, fallback, concurrency, and connection-refused.
- **Replace fire-and-forget `loop.schedule()` with `kota::task_group`**:
Compiler compile tasks, Indexer background indexing + resource monitor,
WorkerPool worker monitors, and socket accept loops now use structured
concurrency. This eliminates manual `alive_count_`/generation counters
and ensures all spawned tasks are joined on shutdown.
- **Fix flaky integration test**: `CliceClient.initialize()` now always
sets `cache_dir` to a workspace-local `.clice/` directory, preventing
stale PCH artifacts from the global `~/.cache/clice/` from polluting
test runs.
## Details
**Compiler peer lifetime**: `Compiler` and `Indexer` previously took
`JsonPeer&` in their constructors, coupling them to a single connection.
They now store a `JsonPeer*` set via `set_peer()`, with null checks
before sending diagnostics/progress. This supports the multi-connection
model where agentic clients don't need diagnostics.
**Socket mode single-LSP enforcement**: `accept_connections()` takes a
`register_lsp` flag; when true, only the first connection gets an
`LSPClient`. All connections get an `AgentClient`. This prevents
multiple LSP sessions from racing on shared server state.
**Structured shutdown**: `Compiler::stop()` cancels in-flight compile
tasks and joins them. `WorkerPool::stop()` signals workers and joins the
monitor task group. `Indexer` uses a `cancellation_source` to stop its
resource monitor when a background indexing run completes.
**Pin kotatsu**: Changed from `GIT_TAG main` + `GIT_SHALLOW TRUE` to an
exact commit hash for reproducible builds.
