fix: show symlinked files under their own name instead of target's name

stripAbsolutePath called filepath.EvalSymlinks on the full path, which
resolved symlinks and caused symlinked files to display under their
target's name. For example, AGENTS.md -> CLAUDE.md would appear as
two CLAUDE.md entries in the document list.

Use the original path for display while still resolving cwd symlinks.

Fixes #965
