#Requires -Version 5.1

.SYNOPSIS
    Factory setup script for Windows hosts.

.DESCRIPTION
    Run this from the HOST PROJECT ROOT after adding factory as a submodule:

        git submodule add https://github.com/custodyzero/factory.git .factory
        .\.factory\setup.ps1

    Layout after setup:
        .factory\     - tooling (git submodule, hidden)
        factory\      - artifacts (features, packets, completions)

    What this script does:
        1. Installs factory dependencies (inside .factory/)
        2. Copies template files to host project root (no-clobber)
        3. Creates artifact directories under factory/
        4. Seeds host-project memory + cache directories
        5. Configures git hooks
