fix(cli): address PR #31 review — 6 issues fixed

Critical:
1. trigger: use Unix socket IPC to daemon instead of direct DB write
   - new daemon-ipc.ts (server) + daemon-client.ts (client)
   - kernel accepts ipcSocketPath, auto-starts IPC server
2. init workflow: validate name (lowercase alphanumeric + hyphens only)

Should fix:
3. getAllWorkflowRuns: SQL query on workflow_runs table instead of O(n) scan
4. limit/offset: robust parseIntArg() helper with NaN handling
5. statusIcon: exhaustive switch with never type check
6. trigger: end-to-end Unix socket tests added

12 new tests. All 224 tests pass.
