Setup Git

Goal: make the target machine provide a working git and fill in the minimum identity configuration.

Follow this process:

• Check whether git --version works. If not, install git first.
• Check git config --global user.name and git config --global user.email; fill them in from ticket context when missing.
• Repair Git authentication only when there is a real credential problem, and avoid overwriting an already working setup.
• Finish with non-destructive commands that confirm the basic Git flow works, and record the effective configuration.
