Add fleet control: service configs, replica floors, monitor, pause/restart

Central fleet.json sets min/max copies. Tree-node keepFloor respawns
until three healthy unpaused replicas remain. CLI and loopback UI
pause, resume, stop, and restart instances that fail health checks.

+Operator control plane for Verae Time × Zapier **runtime** services:
+
+- a **list** of every service and its config file
+- a **central replica spec** (`fleet.json`) — how many copies must be up
+- a **monitor** of active / paused / unhealthy replicas
+- **restart** when a copy is offline or fails `/health`
+- **on / off / pause / resume** per service or per instance
+- **keepFloor** on tree nodes so at least `min` copies stay available (paused copies do not count)
+
+```bash
+cd packages/verae-fleet
+npm test
+node src/cli.js list
+node src/cli.js serve    # http://127.0.0.1:3850/
+```
+
+Against a running daemon:
+
+```bash
+node src/cli.js status
+node src/cli.js pause tree-node-0      # floor starts another tree-node
+node src/cli.js resume tree-node-0
+node src/cli.js restart tree-node-1
+node src/cli.js stop webhook-deliver   # disable that service
+node src/cli.js start webhook-deliver
+```
+
+Zapier cloud apps are listed but **not spawned**. NATS on NS1 is **monitored only** (loopback `:4222`, never a public bind).
