Raise MIN_HOST_SERVICE_VERSION for hosts that lack includeFrom.

Remote hosts at or above MIN_HOST_SERVICE_VERSION but without this change stay selectable. They ignore includeFrom, so a range selection returns the exclusive fromHash..commitHash result and omits the oldest commit's files. Raise MIN_HOST_SERVICE_VERSION to the release that includes this change, with a note in host-version.ts on why.

As per coding guidelines, "Also raise MIN_HOST_SERVICE_VERSION when a change needs a newer host, with a note in that file on why." This change needs a newer host for correct range results.

at line 31:
Update MIN_HOST_SERVICE_VERSION in host-version.ts to the first host release
that supports includeFrom, ensuring older hosts that ignore it are no longer
selectable; add a note there explaining that this minimum is required for
correct range results.

Use the empty tree for the repository's object format.

EMPTY_TREE_HASH is the SHA-1 empty tree. In a SHA-256 repository, git diff cannot resolve it, so an inclusive range that starts at a root commit fails. getChangedFilesForDiff catches that failure and returns [], so the root commit's files are missing from the Changes list. Select the empty-tree ID by object format. For SHA-256 repositories, use 6ef19b41225c5369f1c104d45d8d85efa9b057b53b14b4b9b939dd74decc5321.

Update getChangedFilesForDiff to select the empty-tree ID based on the
repository’s object format: retain the existing SHA-1 ID for SHA-1 repositories
and use the SHA-256 empty-tree ID for SHA-256 repositories. Ensure root-commit
inclusive ranges use the selected ID when computing changed files.

Do not treat a shallow boundary commit as a root commit.

resolveCommitBaseRef uses the empty tree when git rev-list --parents prints no parent. Git omits the parent of a shallow boundary commit, so a non-root commit can take the empty-tree path. The whole boundary snapshot then appears as added files with full-content diffs. Check the raw commit header for a parent line before falling back.

- 569:
Update resolveCommitBaseRef to distinguish a true root commit from a shallow
boundary: when rev-list yields no parent, inspect the raw commit header for a
parent line and reject the incomplete-history case instead of returning
EMPTY_TREE_HASH. Keep the empty-tree fallback only for commits with no parent in
the raw header.
