fix(content): argparse --dry-run for generate_corp_stubs.py; populate cross_refs (#828 nits)

- generate_corp_stubs.py: add argparse with --dry-run (prints planned stub
  creations without writing files) and --help
- calloway-distillery.md: cross_refs → [thrds, mercado-travessia]
- thrds.md: cross_refs → [calloway-distillery, mercado-travessia]
- vins-de-grand-vide.md: cross_refs → [nordmark-skog]
- thalassa-resort-group.md: cross_refs → [the-registry, prometheus-labs]
