Fix single-element list unwrapping in tool content

Browse source 
Single-element lists like [1] were being incorrectly unwrapped to "1"
in unstructured content while multi-element lists remained as lists.
This created inconsistent behavior where the structure was lost for
single items.

This fix ensures lists always preserve their structure in unstructured
content regardless of length, making behavior consistent and predictable.

Also removes pretty-printing from JSON serialization for more compact
output across tools, prompts, and resources.

Fixes #1064
