debug: add detailed logging to tool executor to diagnose OpenAI schema error

Add console.log statements to track:
- Tool parameters array and length
- Generated Zod schema details
- Tool definition structure
- Sanitized tool name
- Complete tools config sent to OpenAI

This will help diagnose why OpenAI is still receiving 'type: "None"'
for empty parameter schemas despite the fix.
