feat: Add torch MCP tools for multi-browser control

- Add torchHandlers.ts with 5 tools:
  - list_torch_clients: list connected browsers with metadata
  - get_torch_status: show current torch holder
  - transfer_torch: transfer control to another browser
  - request_torch: request MCP control
  - release_torch: release MCP control
- Add 'transfer' message type to server torch-handler
- Add torch category to all pages
- Export helper functions from torch.ts
