scripts/ is now a proper package (scripts/__init__.py, added to the wheel's
packages), with each script registered under [project.scripts] using its
bare dashed name (e.g. `uv run migrate-geant-steps`). Tests now import these
modules normally instead of loading them by file path.

The Typer-based giant/cli.py train command now has full feature
parity (dropout, warmup-epochs, validate-steps, shorthand flags),
making the standalone argparse script redundant.
Output space is 9D (post_dir + travel_dir), not 6D; documents the
giant CLI, analysis/validate modules, ROOT-to-parquet conversion
script, cpu/cuda install extras, and the ruff/ty dev tooling.
