macOS manifest: arch-aware Homebrew prefix + variable interpolation support

[darkn3rd]

Summary

Provisioning Manifest features (scriptbox/config)

• Add support to use ERB evaluation in variables: block (resolve_order.rb) so that variables can be referenced throughout rest of manifest with <%= $name %>. Useful for detecting platform, e.g. x86_64 vs arm64, so that variable brew_prefix can be set dynamically.
• macOS manifest:
  • brew_prefix picks /usr/local (Intel) vs /opt/homebrew (Apple Silicon) via RbConfig::CONFIG['host_cpu'], used consistently across Homebrew bootstrap,
  • PATH appends (gawk, grep, bc, gnu-getopt, ruby4), and gem setup
  • Overhaul scriptbox/config/macos.yml: pinned tool versions (python3, ruby4, php, tcl, go), GNU grep/gawk setup, CPAN local::lib setup, Java 17, Wine + winetricks + coreutils for Windows scripting.
  • Support PowerShell cask via darkn3rd/tools/powershell-pkg cask,
  • CLT (Xcode Command Line Tools) install routine cleanup
• Add sudo: support for appends: entries (needed for /etc/shells on macOS)
• Re-add pkgbox/tap/darkn3rd/homebrew-tools submodule, bumped to latest
• Corresponding updates to the Ansible, Chef, and Puppet generators for the new interpolation/variable behavior

Test plan

• Generated and ran the macOS install script on an Intel VM
• Generated and ran the macOS install script on an Apple Silicon VM
• brew_prefix resolves correctly to /usr/local and /opt/homebrew respectively on each
