What's Wrong?

Describe the bug When using the Claude Code CLI, the response output suffers from severe formatting issues. Sentences appear fragmented, with random line breaks and erratic indentation. Specifically, parts of the sentences are cut off or start in the middle of the terminal line (e.g., "...dan destekleniyorum"), and subsequent paragraphs are heavily indented without cause.

To Reproduce Steps to reproduce the behavior:

1. Start a session in the CLI (Windows Terminal / PowerShell).
2. Enter a simple query (e.g., "sen kimsin" / "who are you").
3. Observe the streaming response.

Expected behavior The response should be strictly left-aligned and formatted as a coherent text block, similar to standard CLI outputs.

Screenshots

Environment (please complete the following information):

• OS: Windows (deduced from file path syntax)
• Shell: [PowerShell / CMD / Bash?]
• Claude Code Version: [Varsa versiyon numarasını buraya yaz]

Additional context It seems like the render engine struggles with terminal width calculation or stream buffering, causing the first few characters of lines to disappear or shift incorrectly. The output "onorepo'sunda..." suggests a cut-off of the word "monorepo".
