Adds git repository initialization for Gas Town harnesses:
1. New 'gt git-init' command for existing harnesses:
- Creates comprehensive .gitignore for Gas Town
- Initializes git repository if not present
- Optionally creates GitHub repo with --github flag
2. New flags on 'gt install':
- --git: Initialize git with .gitignore during install
- --github=owner/repo: Create and push to GitHub repo
- --private: Make GitHub repo private
The .gitignore properly excludes:
- Polecats and rig clones (recreated with gt spawn/rig add)
- Runtime state files (state.json, *.lock, registry.json)
- OS and editor files
And tracks:
- Role contexts (CLAUDE.md)
- .beads/ configuration and issues
- hop/ directory
