[BUG] Once an invalid image format is pasted in, all subsequent prompts fail

Environment

• Platform (select one):
• [X] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 0.2.97 (Claude Code)
• Operating System: macOS 15.1
• Terminal: Warp

Bug Description

After pasting in a JPEG, all subsequent prompts yield:

API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.6.content.0.image.source.base64.data: Image does not match the provided media type 
     image/png"}}

Steps to Reproduce

1. Paste JPEG into Claude and press enter. (This should error out)
2. Try any other prompt
3. Still see error prompt. This is unrecoverable as far as I can tell

Expected Behavior

Invalid images are not included in subsequent calls

Actual Behavior

Every request after the invalid image errors out.
