refactor: Unify sync server and combine torch with connection UI

- Consolidate git and torch WebSocket servers on port 4105
- Create separate handlers for git and torch in handlers/ directory
- Combine TorchButton with connection status into single pill button
- Remove StatusBar (now redundant with TorchButton)
- Remove auto-assign torch on register/disconnect
- Remove auto-connect to MCP on page load
- Connection only happens when user explicitly requests torch
