chore(ai): formally include already supported onLanguageModelCallStart and onLanguageModelCallEnd in ToolLoopAgentSettings type

[felixarntz]

Background

ToolLoopAgent already forwards onLanguageModelCallStart and onLanguageModelCallEnd to generateText and streamText, but ToolLoopAgentSettings did not declare them. This appears to be an oversight, given the other lifecycle callbacks were already explicitly included in the ToolLoopAgentSettings type.

Summary

• Add both language model lifecycle callbacks to ToolLoopAgentSettings.
• Add type regression coverage for both callbacks.

End-to-End Verification

N/A. This change formalizes existing runtime behavior.
