chore(presence): heartbeat interval 5s -> 10s

Browse source 
Verlaagt het schrijfvolume naar claude_workers met factor 2. CLAUDE.md noot
toegevoegd dat de Scrum4Me NavBar-drempel (last_seen_at < now() - 15s)
bij 10s interval krap is — daar kan 25-30s een veiliger marge zijn.

## Worker presence
Server-startup registers a `ClaudeWorker` record + starts a 5 s heartbeat; SIGTERM/SIGINT cleans it up. The Scrum4Me NavBar counts active workers via `last_seen_at < now() - 15s`.
Server-startup registers a `ClaudeWorker` record + starts a 10 s heartbeat; SIGTERM/SIGINT cleans it up. The Scrum4Me NavBar counts active workers via `last_seen_at < now() - 15s` — at 10 s interval one missed tick + jitter can flicker the indicator; bump that threshold in Scrum4Me to ≥ 25 s if needed.
| File | Purpose |
|---|---|
| `src/presence/worker.ts` | `registerWorker` (upsert + pg_notify worker_connected) + `unregisterWorker` |
| `src/presence/heartbeat.ts` | `startHeartbeat` — 5 s interval, self-heals by re-registering when record disappears |
| `src/presence/heartbeat.ts` | `startHeartbeat` — 10 s interval, self-heals by re-registering when record disappears |
| `src/presence/shutdown.ts` | `registerShutdownHandlers` — SIGTERM/SIGINT → stop heartbeat + unregister |
| `src/index.ts` | Bootstrap: calls `getAuth` → `registerWorker` → `startHeartbeat` → `registerShutdownHandlers` |
