<#
.SYNOPSIS
  One-time bootstrap for the Tier 2 autonomous sandbox.
.DESCRIPTION
  Clones the main repo to C:\projects\manual_slop_tier2\, sets origin
  to the main repo's local path, copies the agent/command/opencode.json
  templates, installs the git hooks, creates the app-data temp dir with
  restricted ACLs, and creates a "Tier 2 (Sandboxed)" desktop shortcut.
  Idempotent: re-running updates templates and re-fetches, but does not
  destroy existing feature branches in the clone.
.PARAMETER WhatIf
  Show what would happen without making changes.
.PARAMETER MainRepoPath
  Path to the main repo. Default: C:\projects\manual_slop
.PARAMETER Tier2ClonePath
  Path to the Tier 2 clone. Default: C:\projects\manual_slop_tier2
