Markdown Formatter Contract
A PostToolUse hook runs markdownlint-cli2 --fix and then prettier --write on every markdown file written or edited, excluding .llmtmp/, .llmdocs/, SKILL.md, and plan files. Writing to this contract avoids a rewrite, and a rewrite invalidates the in-context copy of the file.
