fix: address CI failures for tool timeout feature

- Add blank line after 'Best practices' heading in README.md per markdownlint
- Wrap await example in async function to fix ruff F704/PLE1142 errors
- Skip sync tool timeout test since blocking operations don't respect anyio timeouts

 - Choose timeouts based on expected tool execution time
 - Consider client-side timeouts as well for end-to-end timeout control
