Add AWS EC2 SSH PowerShell onboarding guide for GFE users Verified PowerShell-only path for new Government-Furnished Equipment users to SSH into the AWS EC2 dev instance over the localhost:2222 tunnel using only built-in Windows 11 OpenSSH (no Git Bash, no installs, no admin). Covers Ed25519 keygen with owner-locked NTFS ACL, public-key handoff, the AWS_EC2_tmcg_ps .ssh/config block, and ssh -v verification, plus MSYS-vs-Windows-OpenSSH client differences, a symptom-to-cause troubleshooting table, and file inventory. Links the guide from Home.md; new alias coexists with the legacy AWS_EC2_tmcg.
