Move .github/copilot-instructions.md to AGENTS.md, and generalize the
wording, so it will apply to Codex CLI, Cursor, OpenCode, RooCode, and
many other AI coding agents.
Also add CLAUDE.md as a symlink to AGENTS.md so Claude Code reads the
same guidance.
Copilot coding agent now supports AGENTS.md custom instructions, as
more coding agents support it. Migrating from GitHub Copilot's custom
instructions file to AGENTS.md will help developers leverage more and
different coding agents than just GitHub Copilot.

The Debian WSL image has stale apt sources pointing to ftp.debian.org
which no longer hosts bullseye-backports. The previous fix ran sed
after the first setup-wsl call, but that call already failed because
additional-packages triggers apt-get update internally.
For wsl_matrix (Debian, Ubuntu):
- Ubuntu: install with additional-packages directly (no apt issue)
- Debian: install without packages first, fix sources.list with sed,
then run apt-get update/upgrade/install manually with retries
- Exclude Debian and Ubuntu-20.04 --lts since node v24+ has exec
format errors on WSL1
For wsl_matrix_unofficial (Alpine):
- Remove the Debian-specific fix entirely (Alpine uses apk, not apt)

This comprehensive guide helps GitHub Copilot better understand and navigate the nvm codebase by providing:
- Complete architecture explanation of nvm's POSIX-compliant design across multiple shells
- Detailed mapping of top-level commands to internal functions (install, use, ls, alias, etc.)
- Comprehensive testing infrastructure guide using urchin framework
- Shell environment setup for bash, zsh, dash, sh, and ksh
- CI environment details for GitHub Actions and Travis CI
- shellcheck setup and usage guidelines
- Development best practices for POSIX compliance and multi-shell compatibility
- Windows support via WSL2, Cygwin, and Git Bash
- Complete internal function categorization and debugging techniques
The documentation covers all aspects of the codebase to enable more accurate AI assistance when working with nvm's complex shell script architecture.
