fix: don't treat empty input as truncation for tools without required fields

Browse Source 
Tools like TaskList, TaskGet have no required parameters, so empty input
is valid. Previously, the truncation detector flagged all empty inputs as
truncated, causing these tools to be skipped and breaking the tool loop.

Now only flag empty input as truncation when the tool has required fields
defined in RequiredFieldsByTool.
