feat: Add torch client identity, early connection and auto-request

- Named clients persisted in localStorage, editable from dropdown
- Auto-request: clients can auto-receive torch when no holder exists
- Early torch init in App.vue (fires before WebMCP, awaited later)
- Deferred torch connection in toolRegistry for race condition safety
- TorchButton rewritten as dropdown with name editor, toggle, client list
- Server broadcasts client names, supports update-name message
- MCP tool handlers display client names
