Create PR Skill v7.0.0

Platform-agnostic automated PR workflow:

1. Analyze code changes and detect logic changes (functions/classes + file stats)
2. Auto-generate Issue + PR titles and descriptions
3. Auto-commit with DCO sign-off (Signed-off-by)
4. Auto-push
5. Auto-create Issue (optional, via API)
6. Auto-create PR with Issue linkage (Fixes #id)

Quick Start

1) Configure Token (one time, for API features)

The script supports multiple platforms via configuration:

# For GitCode/GitLab
git config --global gitcode.token "your_token"
