Give the Agentic Engineer product documentation guidance #574

🤖 Generated by the Agentic Engineer

Outcome

Bundle the original product-documentation skill from devantler-tech/agent-skills#281 once its delivery PR#282 merges. The Engineer should load it when building or maintaining a user documentation site, alongside the appropriate existing framework skill.

Acceptance

• Import the merged canonical skill using native gh skill provenance pinned to its immutable source commit; never hand-copy or edit a synchronized skill.
• Add conditional guidance to the Engineer role without preloading the companion into every run or changing its three core skills.
• Update the plugin catalogue, release notes, cache version and generated desired-state digests through the existing tools.
• Validate manifest/catalogue parity and the official skill specification, review at the exact head, and merge through normal gates.
• Distinguish reviewed source delivery from installation or runtime adoption in consuming deployments.

Part of #51. Depends on devantler-tech/agent-skills#282.
