Inline security model link in output-injection side quest to satisfy no-footer guideline

[Copilot]

The side-quest doc included a trailing blockquote “See …” reference, which violates the guideline that documentation links must be inline rather than in footer-style sections. This updates the page so the security architecture reference is attached directly to the relevant sentence.

• Documentation guideline compliance

  • Removed the trailing blockquote reference at the end of workshop/side-quest-17-06-output-injection.md.
  • Kept the content intent unchanged while eliminating the footer-style pattern flagged by the guidelines enforcer.

• Link placement update

  • Added the security architecture link inline at the nearest sentence discussing the full security model (anchored on “security model”).

gh-aw keeps the agent read-only and limits which follow-up writes safe-outputs may apply in its [security model](...).

• Fixes [guidelines] side-quest-17-06-output-injection.md: trailing blockquote reference violates no-footer rule #2499
