[Bug] Markdown table and list rendering broken in v2.0.73

Bug Description
ISSUE: Markdown table and list rendering broken in v2.0.73

SYMPTOMS:

• Tables only show last row or garbled fragments (e.g., "splayed |")
• Numbered lists cut off at beginning of lines
• Bullet points with sub-items display broken structure

CONFIRMED NOT MY SYSTEM:

• Ran PowerShell direct table output - displays all rows correctly
• Claude Code's raw markdown output shows complete data
• Claude Code's rendered output shows only fragments
• Diagnostic test proves terminal is fine, bug is in Claude Code's markdown renderer

STEPS TO REPRODUCE:

1. Ask: "Show a markdown table of 5 countries with capital and population"
2. Only last row displays
3. Ask: "Show it as raw markdown"
4. All rows appear correctly - proves data is generated, rendering is broken

IMPACT:

• Claude Max subscriber
• Cannot use structured data outputs for business work
• Core feature unusable

Environment: Windows 11, Windows Terminal, PowerShell

Environment Info

• Platform: win32
• Terminal: null
• Version: 2.0.73
• Feedback ID: 64588c86-4f3f-47c2-b9f6-2950530fa766
