Add dedicated reference for root AGENTS.md to agent-docs linking patterns with
anti-patterns and explicit reference requirements. Update SKILL.md core rules to
emphasize directional, explicit references and minimal reference depth. Refine
template structures in inventory-doc-template.md and root-agents-template.md to
enforce clearer scope sections and required reading lists. Update agent interface
metadata to reflect focused maintenance scope.
Add the Bluecraft Agentic Docs skill with guidance for maintaining
root `AGENTS.md` files and `agent-docs/` trees.
Include OpenAI agent metadata plus reference templates and checklists
for root routing, rule docs, inventory docs, and refactor validation.
