Terminal Cursor Movement Enhanced

What: Terminal cursor positioning now uses semantic event types instead of raw ANSI control sequences

Details:

• Replaced raw stdout strings (like \r for carriage return, \b for wrap handling) with semantic event types
• New event types: resolvePendingWrap, carriageReturn, cursorMove
• Supports returning multiple terminal events per transaction for more complex operations
• Improves code maintainability and testability while producing identical terminal output
• Evidence: Replaced Hk0() at line 77408 with Ii0() at line 77184, updated supporting class from zk0 to Yi0
