chore: audit and fix agent config, codebase docs, and create-pr skill

- Add missing /pre-commit-check and /blog-post skill triggers to AGENTS.md
- Switch create-pr.md from --body-file to HEREDOC, ban /tmp file writes
- Add Season constants and field to types.md, clarify handler count
- Add cross-reference from patterns.md test section to AGENTS.md
- Bump verification dates on codebase docs

 ## PR conventions
 
-- **Use `--body-file`**: Write the PR body to a file and pass
-  `--body-file` instead of `--body`. This avoids shell-quoting issues
-  that silently corrupt markdown.
+- **Use a HEREDOC for the body**: Pass the PR body via a HEREDOC to
+  avoid shell-quoting issues. Do not write temporary files to `/tmp`.
+  Example: `gh pr create --title "..." --body "$(cat <<'EOF'` ...
+  `EOF` `)"`
 - **Rebase merges only**: This repo uses `gh pr merge --rebase`. No merge
   commits, no squash merges.
 - **No "Test plan" section**: CI covers tests, lint, vet, and build.
