## Summary
- replace the root `AGENTS.md` symlink with a real file
- move the agent instructions out of `.github/copilot-instructions.md`
into `AGENTS.md`
- trim the content down to concise, repo-specific guidance and add a
short repository orientation
## Testing
- not run (docs-only change)
This commit splits up the "normal" cache containing the dependencies and
the "python" cache containing the python binaries. This will lead to a
one-time invalidation of caches.
Closes: #713
