Replace the five separately-hyphenated uv entry points (steps-to-parquet, steps-to-parquet-parallel, migrate-geant-steps, bump-dataset-version, create-root-files) plus the unregistered hparam_scan.py with one `dwarf` command exposing convert/migrate/bump-gen/bump-schema/status/ update-manifest/create-manifest/make-root/hparam-scan as subcommands. Each scripts/*.py module now only holds argparse-free business logic; scripts/dwarf.py wires it up with Typer, matching giant/cli.py's style. `dwarf convert` merges the old serial/parallel conversion scripts behind a --jobs flag (default 1: sequential with plain -o; >1: dataset-layout fan-out via subprocess).
