fix(ci): repair branch gates after the master merge

- regenerate docs/module-graph.md for the attachment packages
- pack @deepseek-ai/dsh-attachment in the packed-install e2e closure so npm
  resolves the new dsh-llm peer from the tarball set instead of the registry
- gate the pi-ai anthropic e2e profile strictly on ANTHROPIC_API_KEY: the
  DeepSeek endpoint does not serve anthropic-messages, so the DEEPSEEK_API_KEY
  fallback turned the keyless skip into a 404 across the whole suite
