Text pasted into console gets silently truncated/cut off

Bug Description

When pasting text into the Claude Code console (Windows 11), the pasted content is frequently silently truncated — the end of the pasted text is cut off with no warning or indication that this has happened.

The user has to guess whether the full text made it in or not, and often has to re-paste content in smaller chunks as a workaround.

Impact

• Wastes significant user time (have to re-paste, verify, break into chunks)
• Causes incorrect AI responses when context is incomplete (AI doesn't know text was cut off)
• Especially problematic when pasting email threads, legal documents, or other multi-paragraph content

Reproduction

• Paste a moderately long block of text (e.g., a multi-email thread) into the Claude Code input
• The end of the pasted text is silently dropped
• No error, no warning — it just stops mid-sentence

Environment

• Windows 11 Pro 10.0.26200
• Claude Code CLI
• Has been happening for months
• Does NOT happen in other tools (e.g., Codex)

Expected Behavior

All pasted text should be captured in full, or at minimum the user should receive a clear warning that input was truncated.

Workaround

User currently breaks pastes into multiple smaller messages, which is time-consuming and disrupts workflow.
