Wrong Examples in Generic Methods

[Flipez]

Every literal type documentation repeats the same generic methods section, but with incorrect examples:

## Generic Literal Methods (in array.md, hash.md, etc.)
### to_s()
<CodeBlockSimple input='"test".type()'  // STRING example in ARRAY docs!

Recommendation:

• Create a single "Generic Object Methods" page
• Link to it from each literal type page
• Show type-appropriate examples for each type
