Introduce docs/dev-notes/ for living design notes on unmerged feature
branches (one Markdown file per branch), so collaborators and the AI agents
they work with can pick up a branch's context from the diff. Documented in
AGENTS.md and a directory README; seeded with the opening-template-on-type
note.
Generated with the assistance of an AI coding tool.
