Subject: [PATCH 1/2] surface: respect semantic prompt boundaries for links

Link detection currently expands the clicked location to a full line
before running the configured regexes. When semantic prompt markers
are present, this can cause prompt text and neighboring content to be
matched together even though they are distinct semantic regions.

Use semantic prompt boundaries when selecting the text to inspect for
link matching. This keeps prompt text separate from the content beside
it and avoids folding prompt text into double-click link/path
selection.

Add a regression test that models a prompt and command on the same
line and verifies the prompt region and input region remain separate.
