From: Xing Xin <xingxin.xx@xxxxxxxxxxxxx> This commit passes `VERIFY_BUNDLE_FSCK_FOLLOW_FETCH` to `unbundle` in the fetching process, including: - `transport.c:fetch_refs_from_bundle` for direct bundle fetches. - `bundle-uri.c:unbundle_from_file` for bundle-uri enabled fetches. This addition ensures a consistent logic for object verification during fetch operations. Tests have been added to confirm functionality in the scenarios mentioned above.
