Using images (like for testing UX changes) often results in the CLI getting into a broken state

### Describe the bug

1. Create a UX application with Claud Code CLI
2. Request changes to the UX
2. Ask it to use screenshots to self-validate if the code changes

Eventually you'll start seeing multiple errors on each request like:
"Images and/or native document attachments were removed from the request due to size constraints. Please use smaller image or document files."

I'm guessing it's the large image files sitting in context. not sure how

### Affected version

GitHub Copilot CLI 1.0.70-0

### Steps to reproduce the behavior

1. Create a UX application with Claud Code CLI
2. Request changes to the UX
2. Ask it to use screenshots to self-validate if the code changes

Eventually you'll start seeing multiple errors on each request like:
"Images and/or native document attachments were removed from the request due to size constraints. Please use smaller image or document files."

### Expected behavior

CLI should manage image context aggrressively, using compression, compaction, etc before showing error message.

### Additional context

_No response_

Start by reproducing the issue in GitHub Copilot CLI 1.0.70-0 using repeated UX changes and screenshots. Then trace how image attachments are retained and how the size-constraint error is surfaced. Done means continued requests no longer leave the CLI reporting repeated image-size errors after it has managed the accumulated image context.
