GitHub Multi-Account SSH

Use this skill when the user works with multiple GitHub identities and any of these happen:

• gh repo create targets the wrong owner
• git push fails with Permission denied (publickey)
• the repository remote uses github.com but the machine is configured with SSH host aliases like dinghao.github.com
• gh is authenticated as one account while git or SSH is effectively using another

Goal

Make GitHub ownership, CLI auth, git author identity, and SSH transport line up cleanly.
