a. create <branch> from main's pinned commit (refuses if main moved, or if <branch> exists at another base)
b. upload_large_folder(<staged>, revision=<branch>) (resumable; commits only to <branch>)
c. one commit on <branch> deleting the v1 files that v2 replaces; aborts if any path to delete is not a
v1 data file / v1 split manifest / the stray .wt files
usage: v2_upload.py <repo_id> <main_sha> <branch> <staged_dir> [a|b|c ...]
