Pull Request: Fix Typo in AssistantStreamEvent Variant

Summary

This PR fixes a typo in the AssistantStreamEvent enum:
Renames TreadCreated to ThreadCreated for better consistency and readability.

---

Changes

• Enum Variant Renamed

  • Before: TreadCreated(ThreadObject)
  • After: ThreadCreated(ThreadObject)

• Event Handling Updated

  • The match arm for the "thread.created" event now uses AssistantStreamEvent::ThreadCreated instead of the misspelled variant.

---

Motivation

• Consistency & Readability
  The previous variant name TreadCreated was a typo and did not match the intended naming convention. This change ensures the code is self-explanatory and maintains consistent terminology.
• Maintainability
  Fixing typos in public APIs and enums helps prevent confusion and potential bugs in the future.

---

Impact

• All usages of AssistantStreamEvent::TreadCreated should be updated to AssistantStreamEvent::ThreadCreated.
• No functional changes were made; this is strictly a naming correction.

---

Reference

-    TreadCreated(ThreadObject),
+    ThreadCreated(ThreadObject),
