Two E2E tests that exercise the full sidebar agent flow with real Claude:
- sidebar-navigate: POST /sidebar-command asking Claude to describe a fixture
page, verify it responds with page content through the chat buffer
- sidebar-url-accuracy: POST with activeTabUrl differing from Playwright URL,
verify the queue prompt uses the extension URL (the core bug fix)
Both registered as periodic tier (~$0.80 total, non-deterministic).
