/**
* Layer 4: E2E tests for the sidebar agent.
*
* sidebar-url-accuracy: Deterministic test that verifies the activeTabUrl fix.
* Starts server (no browser), POSTs to /sidebar-command with different activeTabUrl
* values, reads the queue file, and verifies the prompt uses the extension URL.
* No real Claude needed — this is a fast, cheap, deterministic test.
*
* sidebar-navigate: Full E2E with real Claude (requires ANTHROPIC_API_KEY).
* Starts server + sidebar-agent, sends a message, waits for Claude to respond.
* Tests the complete message flow through the queue.
