Summary

• Add independent tmux and vim Dev Container Features that install the relevant Debian/Ubuntu packages.
• Use standard host dotfile paths:
  • tmux: ~/.tmux.conf → container ~/.tmux.conf (read-only)
  • Vim: ~/.vimrc → container ~/.vimrc (read-only)
  • Vim: ~/.vim/ → container ~/.vim/ (read-write)
• Support Vim configurations that manage plugins and runtime/undo data inside ~/.vim/.
• Make post-create setup idempotent and refuse to replace unrelated existing configuration.
• Keep setup scripts focused on real Dev Container mount paths, without test-only overrides.
• Include usage documentation and lightweight JSON/shell syntax validation only. No custom configuration-link test harness.

Requirements and security considerations

• The bind-mount sources ~/.tmux.conf, ~/.vimrc and ~/.vim/ must exist on the host before starting a container.
• Neither Feature mounts the host HOME directory as a whole.
• Writable ~/.vim/ permits container processes to modify host Vim configuration and plugins; this is an explicit exception to workspace-only isolation.
• Optional files such as ~/.vimrc.local are not mounted automatically.
• The install scripts require Debian/Ubuntu (apt-get).

Verification

• GitHub Actions validates Feature metadata JSON and Bash script syntax.
• Container lifecycle, host mount permissions, and actual tmux/Vim startup remain unverified; test through a real Dev Container before merging.
