Create MR

Create a GitHub pull request from the current branch by reading the repository state, respecting any PR template, and verifying the created PR.

Workflow

1. Detect PR Template

Search for a PR template in this order:

1. .github/PULL_REQUEST_TEMPLATE.md
2. .github/PULL_REQUEST_TEMPLATE/*.md (pick the first match)
3. PULL_REQUEST_TEMPLATE.md
4. docs/PULL_REQUEST_TEMPLATE.md

If a template is found, read it and use it as the base structure for the PR body. Preserve all template sections and fill them from the actual changes.

If no template is found, use the default body format below.
