Current behavior: When devcontainer CLI is not found in PATH, the command fails with an error message telling users to install it manually. New behavior: The CLI resolution now follows a progressive fallback: 1. Check if devcontainer is in PATH 2. Check if devcontainer.path is set in config and binary exists 3. If npm is available, prompt user to install CLI locally 4. Install to ~/.local/share/headjack/devcontainer-cli/ and save path to config Also extracts the huh-based prompter from internal/auth into a shared internal/prompt package for reuse across the codebase. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
