* feat(tailscale): add connect/disconnect/exit-node/LAN-access backend
The Tailscale backend previously exposed only read-only status
(tailscale.getStatus, tailscale.refresh). This adds write actions through the
existing tailscale.com/client/local integration:
- tailscale.connect / tailscale.disconnect (EditPrefs WantRunning)
- tailscale.setExitNode (EditPrefs ExitNodeID; empty id clears it and any
legacy ExitNodeIP, mirroring `tailscale set --exit-node`)
- tailscale.setAllowLanAccess (EditPrefs ExitNodeAllowLANAccess)
The manager's client interface gains GetPrefs/EditPrefs; fetchState merges
ExitNodeAllowLANAccess from prefs, and Peer exposes ExitNodeOption so the UI
can list exit-node-capable peers.
* feat(tailscale): expose the new actions in TailscaleService
Adds connectTailscale/disconnectTailscale, setExitNode/clearExitNode and
setAllowLanAccess wrappers, plus derived exitNodeOptions/currentExitNode and the
exitNodeAllowLanAccess state. Write-action errors surface via ToastService.
* feat(tailscale): add connection, exit-node and LAN-access controls to the widget
The control-center widget toggle was a no-op. It now connects/disconnects, and
the detail panel gains a connection status row with a connect/disconnect button,
an exit-node picker and a LAN-access toggle.
* feat(tailscale): add Tailscale control center widget
Full-stack Tailscale integration for DMS control center:
Backend (Go):
- Event-driven manager via WatchIPNBus (no polling)
- Reconnects with exponential backoff when tailscaled unavailable
- Typed conversion from ipnstate.Status to QML-friendly IPC types
- Testable via tailscaleClient interface with mock watcher
- Manager cleanup in cleanupManagers()
- 19 unit tests
Frontend (QML):
- TailscaleService with WebSocket subscription
- TailscaleWidget with peer list, filter chips, search
- Copy-to-clipboard for IPs and DNS names
- Daemon lifecycle handling (offline/stopped states)
Dependencies:
- Add tailscale.com v1.96.1 (official local API client)
- Bump Go to 1.26.1 (required by tailscale.com)
* cleanups
