Render symlinks in the workspace file tree with a distinct chain-link
icon (vs regular file/folder icons), and show "Symlink → {target}" on
hover with long targets middle-elided. Directory and file symlinks are
both handled; regular entries keep their normal icons.
Rebased onto master (v0.51.466) and code-diff verified byte-identical to
the contributor's PR head before staging.
