lukaszraczylo a81482d06a fix: address 15 additional hang vectors found during deep audit (#45)
MCP server (5 fixes):
- Move semaphore acquisition inside goroutine so main loop stays
  responsive when all slots are taken
- Add 10s write timeout to sendResponse to prevent pipe deadlock
  when Claude Code pauses reading stdout
- Send fallback JSON-RPC error when json.Marshal fails instead of
  silently swallowing the error and leaving caller waiting forever
- Silence unknown notification methods (req.ID == nil) instead of
  sending unsolicited error responses that may desync the host
- Return MCP isError content for tool failures instead of top-level
  JSON-RPC error, matching the MCP specification

Vector/embedding (3 fixes):
- Move EmbedBatchWithContext call before writeMu.Lock in AddDocuments
  so ONNX inference runs outside the write lock
- Replace singleflight.Do with DoChan + ctx select in both
  getOrComputeEmbedding and UnifiedSearch so callers can bail out
  independently when their context expires
- Add activeQueries atomic counter; skip cache warming when user
  queries are in-flight; reduce warming timeout from 5s to 2s

Hooks (4 fixes):
- Cap EnsureWorkerRunning to 15s hard deadline with context; reduce
  StartupTimeout from 30s to 10s; reduce port-in-use retries
- Fix nil dereference panic in user-prompt hook when initResult is
  nil (non-JSON worker response); use comma-ok assertions
- Use package-level hookClient/healthClient with DisableKeepAlives
  to prevent FD leaks in short-lived hook processes
- Set SysProcAttr{Setpgid: true} to detach worker from hook process
  group, preventing kill-cascade from Claude Code

Worker/DB (3 fixes):
- Replace os.Exit(0) in MCP config watcher with context cancellation
  for clean protocol shutdown
- Add 60s context.WithTimeout around ProcessObservation calls in
  processAllSessions to prevent hung CLI subprocesses from blocking
  the queue processor forever
- Set explicit PRAGMA wal_autocheckpoint=1000 and add PASSIVE WAL
  checkpoint to Optimize() to prevent checkpoint stalls

Adds 20+ regression tests across all fix areas.
