[Bug] Text rendering cut off on left side of terminal output on Windows

Bug Description
Text is consistently cut off on the LEFT SIDE of the terminal, causing missing characters at the beginning of lines. This happens regardless of terminal configuration.

IMPACT:

• Instructions and responses are incomplete and unreadable
• Makes Claude Code completely unusable
• Affects basic functionality and user experience

WHAT I'VE TRIED (ALL FAILED):
✓ Updated to latest version (2.0.73)
✓ Ran claude doctor
✓ Ran claude migrate-installer
✓ Ran /terminal-setup
✓ Tested on Windows Terminal, Command Prompt, and PowerShell
✓ Adjusted padding settings (tried 0,0,0,0 and various combinations)
✓ Changed fonts and font sizes
✓ Maximized window to full screen
✓ Reinstalled multiple times using different methods

SYSTEM DETAILS:

• OS: Windows 11 (latest updates)
• Claude Code: v2.0.73
• Terminals tested: Windows Terminal, Command Prompt, PowerShell
• Issue: Text consistently truncated on left margin

TECHNICAL OBSERVATION:
This appears to be a padding/margin rendering conflict between Claude Code's UI formatting and Windows Terminal's text rendering engine. The issue persists across ALL Windows native terminals, suggesting a fundamental compatibility problem with Windows terminal APIs.

EXAMPLES OF MISSING TEXT:

• "ll, or Windows Terminal" → should be "shell, or Windows Terminal"
• "ackground. Prosesnya" → should be "background. Prosesnya"
• "ill then show" → should be "will then show"
