fix(vscode): refresh config after marketplace MCP install/remove

After installing or removing an MCP from the marketplace, the agent
behaviour settings tab was not updating because fetchAndSendConfig()
was never called. Only fetchAndSendAgents() was called, leaving the
config cache stale. This clears cachedConfigMessage and fetches fresh
config in parallel with agents.
