v1.91.369.0 fix: gstack-wtree works when .bun/ is gitignored (GST-449) (#3685)

* gstack-wtree: exclude .bun only when it exists and is not gitignored (GST-449)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* gstack-wtree: ask the ignore rules alone (--no-index) so a tracked file under an ignored .bun/ still fingerprints (GST-449)

* changelog: GST-449 fragment covers the tracked-file case
