Alexandru Dima 678aeb1c87 Add agent instructions for opaque editor background and decorations (#321271) ...

Document two antipatterns fixed in #320913 so AI agents avoid them and
Copilot Code Reviews flag them:

- `.monaco-editor-background` must be opaque (never transparent), otherwise
  the reverse-rounded selection corners break and performance suffers.
- Editor highlights should use regular decorations with inlineClassName/className;
  registerDecorationType/setDecorationsByType is reserved for the ext host API.
