Network requests happening before the --autoconnect handshake happened are not showing up in get_network_request

Description of the bug

• human opens devtools and selects a network request in there
• AI agent is using --autoconnect
• Human prompts with something like " tell me what you know about the network request I have selected in chrome devtools" in their AI agent
• AI agent will start --autoconnect handshake, which the human accepts
• tool get_network_request is called and returns empty

It makes sense that this happens, as the MCP server has no access to network requests that happened before its initialization and connection with Chrome. It's frustrating though, so maybe we can document this somehow?

Extra checklist

• I want to provide a PR to fix this bug

No file or test is named in the issue. Start by reviewing the documentation for --autoconnect and get_network_request, then document that requests made before the handshake are unavailable to the MCP server; done means this limitation and its timing are clearly explained.
