Add update-manifest and create-manifest subcommands to bump_dataset_version

update-manifest rewrites the schemaN component in existing manifest files to a
specified or auto-detected highest schema, verifying all target files exist before
writing. create-manifest builds a new manifest from explicit parquet file paths,
supporting --pool/--type (full|holdout|dev) to derive the output path from root,
and enforcing holdout isolation by checking for cross-manifest overlap whenever a
holdout manifest is involved.
