# REVITHION-STARTUP.ps1 — DevTeam6 Copilot CLI Session Launcher
# ============================================================================
# Author:  SpiralCloudOmega
# Repo:    SpiralCloudOmega/DevTeam6
# 
# PURPOSE:
#   Double-click (via .bat wrapper) to instantly restore your Copilot CLI
#   development session for REVITHION STUDIO. This script:
#     1. Displays system status (RAM, GPU, disk)
#     2. Checks WSL availability and services
#     3. Launches WSL Ubuntu with the session-startup.sh companion script
#     4. That script runs `copilot --resume` to restore your last session
#
# AFTER SESSION RESTORES:
#   - Type /yolo to enable autonomous execution mode (no confirmation prompts)
#   - Type /fleet to enable parallel sub-agent dispatching
#   These must be enabled manually each session.
#
# USAGE:
#   Option A: Double-click REVITHION-STARTUP.bat (recommended)
#   Option B: Right-click this .ps1 → "Run with PowerShell"
#   Option C: powershell -ExecutionPolicy Bypass -File REVITHION-STARTUP.ps1
# ============================================================================
