fix(cli): tool summaries show wrong paths when HOME=/ or the home is a path prefix (#162483)

Fixes #162438.

`shortenHomeInString` now replaces the home directory only at a path boundary. With HOME=/home/al, `/home/alice/...` is left alone; with HOME=/, slashes are no longer turned into `~`. `/home/al/x` still becomes `~/x` and the exact home path still becomes `~`.

Proof: real CLI in secretless Docker (`openclaw reset --scope config --dry-run`). main printed `~ice/p162438.json` and `~p162438~root.json`; this PR prints the correct paths. Regression test fails on main and passes here.
