• Analyze the issue: Kiota generates conversation starters in API plugins when it shouldn't
• Identify the root cause: In GetManifestDocument() method, conversation starters are always added regardless of plugin type
• Modify GetManifestDocument() to not add conversation starters for API plugins
• Update tests to verify that API plugins don't generate conversation starters
• Verify that other plugin types still generate conversation starters correctly
• Run existing tests to ensure no regressions
• Create verification test to demonstrate the fix works correctly
• Restore original project configurations
• Add changelog entry for the fix

Summary:
Successfully implemented the fix to prevent API plugins from generating conversation starters. The change was minimal and surgical:

1. Root Cause: The GetManifestDocument() method was always generating conversation starters regardless of plugin type
2. Fix: Removed conversation starters logic from GetManifestDocument() since it's only used for API plugins
3. Testing: Updated test expectations and verified all 93 plugin tests pass
4. Verification: Created comprehensive test showing API plugins no longer generate conversation starters while preserving all other functionality
5. Documentation: Added changelog entry under the Unreleased section

Before: API plugins included conversation_starters array in capabilities
After: API plugins have empty capabilities object (no conversation starters)

The fix addresses the exact issue described in #6946 with minimal code changes and full backward compatibility.

Fixes #6946.
