Home page: quote the Cheat Sheet's definition of GRC Engineering; nav points Teachings at the Cheat Sheet (#43)

- Adds a styled definition block between the manifesto's first and second
  paragraphs, quoting the GRC Engineering definition from
  cheatsheet.grc.engineering with its blue/orange highlights, links to the
  Cheat Sheet's Governance/Risk/Compliance terms, a source line pointing at
  #grc-engineering, and an "Explore the Cheat Sheet" button. Light and dark
  schemes both styled.
- Replaces the "Learning Hub" nav entry with "Teachings", linking to
  cheatsheet.grc.engineering/#teachings. learning-hub.md is left in place
  (no longer in the nav) so existing links to /learning-hub/ keep working.

 GRC Engineering is a step-change evolution in security governance, risk, and compliance (GRC), and related disciplines such as trust and assurance. It’s more than just “GRC + writing code.”  It’s a fundamental shift in how GRC is done, one that fully embraces an engineering mindset (broadly speaking), [systems thinking](https://en.m.wikipedia.org/wiki/Systems_thinking) and [design thinking](https://en.m.wikipedia.org/wiki/Design_thinking), and a customer-centric focus around how best to deliver GRC outcomes.

 We see the [organic interest](https://www.reddit.com/r/cybersecurity/comments/18efir2/grc_engineering/) and momentum that is growing around GRC Engineering as an opportunity to bring our community together with a shared definition of what GRC Engineering is as well as a shared focus on advancing it together before it’s co-opted and constrained by commercial interests.
 
 As a group of impassioned GRC practitioners, we seek to propel GRC into the modern era so it can:
