Test T3 web and desktop

Use T3's built-in Browser panel for verification. If its tools are absent or the panel reports unavailable, explain the blocker and stop verification. Do not install or switch to another automation system. For native mobile testing, use test-t3-mobile.

Start the app

Reuse this task's healthy dev server. Otherwise run vp run dev from the repository root and retain its terminal session. Use the worktree's ignored .t3 state and read the actual ports and pairing URL from the dev-runner output. Never run against ~/.t3/userdata or set VITE_HTTP_URL or VITE_WS_URL.

Test with meaningful project and thread data. Read references/sqlite-fixtures.md only when inspecting or seeding SQLite. Stop the test server before direct fixture writes.
