fix(mcp): configure mcp_client allowlist on project switch

Previously mcp_client.configure() was only called during ai_client.send()
which meant GUI buttons (Slices/Inspect) couldn't access files when
project was switched to an external project like gencpp. Now _switch_project
reconfigures mcp_client with the new project's root and file_items.
