fix(tasks): address Copilot review feedback

- Fix escaped-backtick rendering bug in governed example (tasks.md:175):
  use double-backtick outer span so inner backtick displays correctly
- Add missing info strings (text) to four bare fenced code blocks in
  implement.md (MD040 compliance) - pre-hook and post-hook sections
