fix(typescript): Remove problematic JSDoc example causing parse error

Removed JSDoc example from saveContentCache that was causing
TypeScript parser to fail with 'Unterminated template literal' error.

The example code block was being parsed as actual code instead of
JSDoc comment, causing parse errors.

Verification:
- TypeScript compiles ✅
- Build passes ✅
