GitHub Copilot Workspace

Copilot reads .github/copilot-instructions.md, not AGENTS.md, so add a short pointer file rather than duplicating content:

<!-- .github/copilot-instructions.md -->
Follow the rules in /AGENTS.md and the roles in /SKILLS.md for every task in this
repository.

Keep the pointer file minimal — Copilot loads it into every request's context, so don't paste the full AGENTS.md content in twice.
For instructions scoped to a specific path (e.g. only *.test.ts), Copilot also supports .github/instructions/<name>.instructions.md files with an applyTo: glob in frontmatter — use these for anything that shouldn't apply repo-wide, keeping the cross-tool AGENTS.md general.
