Context

BrowserTrace now leads with uvx as the fastest trial path before PyPI publishing is enabled. Some users will not have uv / uvx installed yet.

Task

Add a short troubleshooting note to README.md or examples/README.md for users who see uvx: command not found.

Suggested direction

Keep it short and link to the official uv installation page rather than copying a long installer script. Mention that users can also use the persistent GitHub-tag pip install path already documented in the README.

Acceptance criteria

• The docs explain what to do if uvx is missing.
• The note does not claim PyPI is available before browsertrace is published.
• Existing uvx and GitHub-tag install commands remain intact.
• Run uv run --python 3.11 --extra dev pytest -q before opening a PR.
