fix(anthropic): skip tool calls with empty names to prevent API errors (#1739)

Browse source 
When building parameters for Anthropic API calls, tool calls with empty
names would cause 400 Bad Request errors with the message:
'tool_use.name: String should have at least 1 character'

This fix adds a check to skip tool calls that have empty names, preventing
the API error and allowing the conversation to continue normally.

Fixes #1658
