[2026-04-27] bugfix | Fix PR Body Newlines and Update SCHEMA
Discovered that executing gh pr create with inline --body parameters and literal \n characters caused raw strings like \n\n to appear in GitHub Pull Request descriptions.
Deployed an automated Python script (fix_prs.py) to scrape the last 20 PRs, identify any with literal \n tokens, replace them with actual system newlines, and patch the GitHub PRs via the CLI.
Added a strict operational rule to SCHEMA.md mandating that autonomous agents must always use --body-file or Heredocs when generating GitHub issues/PRs to preserve natural formatting.
