Integrate Napkin with agent skills

Run this immediately after setup-matt-pocock-skills. Add Napkin project memory without duplicating the issue tracker, triage labels, domain glossary, or ADR rules.

This is prompt-driven. Explore, present findings, take one answer at a time where a choice exists, show exact drafts, then write only after approval.

1. Guarded preflight

Read the Napkin integration contract before the first Napkin command. It records the mutation, layout, indexing, template, Pi-extension, and version-drift branches.

Establish the repository root and inspect:

• AGENTS.md and CLAUDE.md
• docs/agents/issue-tracker.md, docs/agents/domain.md, and optional docs/agents/triage-labels.md
• NAPKIN.md
• .napkin/ and .obsidian/.napkin/ in the current directory and each ancestor
• .obsidian/
• root README, manifests, existing domain docs, and the folders that reveal the repository's purpose
• command -v napkin and napkin --version
