File links to absolute paths outside project root are not clickable

When Claude formats a file reference as a markdown link with an absolute path outside the current working directory (e.g. C:\Users\...\CLAUDE.md), the link is not clickable in the Claude Code Desktop interface. Links only appear to work for paths relative to the project root.

Expected: Absolute paths to files on disk should open in the editor, or Claude should not format them as clickable links if they won't work.

Additional issue: Right-clicking the link to copy the path returns an internal Claude path rather than the actual filesystem path, so there is no easy workaround to open the file manually.
