setup.ps1

# cc-settings bootstrap for Windows - PowerShell mirror of setup.sh.
# All install logic lives in src\setup.ts. This file exists to:
#   1. Handle `irm ... | iex` by cloning the repo if not already on disk.
#   2. Ensure Bun is installed.
#   3. exec `bun "$Repo\src\setup.ts" --source="$Repo" @Args`.
#
# Remote one-liner (default full install; clone the repo to pass flags):
#   powershell -ExecutionPolicy Bypass -c "irm https://raw.githubusercontent.com/darkroomengineering/cc-settings/main/setup.ps1 | iex"
#
# Flags (forwarded to src\setup.ts):
#   --light           light tier: raw CC + statusline + share-learning only
#   --rollback[=TS]   restore newest backup (or a timestamp match)
#   --dry-run         print planned actions only
#   --status          print installed vs packaged version info
#   --migrate-only    backup + settings merge + sentinel; skip file copy
#   --interactive     prompt on settings.json conflicts (also: $env:CC_INTERACTIVE=1)
#   --help, -h
