refactor: Modularize build.zsh into separate setup scripts

Separated build.zsh into 3 clear parts:

1. build.zsh (Arch Linux base construction)
   - archiso bootstrap
   - pacstrap base system
   - install base packages
   - install Claude Code

2. cfg/setup-user.sh (User setup)
   - Create ai user
   - Configure sudoers
   - Setup auto-login
   - Configure zshrc and auto-start

3. cfg/setup-claude.sh (Claude/aigpt setup)
   - Install aigpt
   - Configure MCP
   - Setup symlinks
   - Initialize database

Benefits:
- Each file has a single, clear responsibility
- Easier to maintain and modify
- Can skip/customize setup steps if needed
- GitHub Actions simplified to just run build.zsh
