test: add tests for link replacement optimization

Added integration tests for the roam link replacement functionality
to validate the performance optimization that limits the scope of
link replacement by searching specifically for "[[roam:" instead
of any org link bracket pattern. The tests ensure:

1. Special regex characters in buffer content don't break the
   search functionality when using search-forward
2. Only roam: links are processed, not other link types like
   file: or https:

These tests validate the optimization maintains correctness while
improving performance by avoiding unnecessary replacement attempts
on non-roam links.
