Subject: [PATCH] feat(code): add /code:pr command to generate pull requests
 (#101)

Add PR generation command that:
- Auto-generates title from branch name
- Creates body with commit list and changed files
- Supports --draft flag for draft PRs
- Supports --reviewer flag to request reviews

Migrated from core-claude PR #46.
