PR review feedback: Step 3 gave no concrete guidance on what good
AGENTS.md content looks like, and the skill had no substantive
references file (only provenance bookkeeping in sources.md), unlike
sibling kyberforge skills. Adds section-by-section content guidance,
the worked example, and monorepo precedence rules synthesized from
the agentsmd research corpus.

Creates/updates a target repo's AGENTS.md by exploring real repo
conventions, supports nested monorepo placement, closes out via
agentsmd-audit, and composes into provider-adapter-author for
provider-file reconciliation. Completes the three-skill trio from
ADR-0012.
