2e84f1ece0 test: fix ACD test race condition and add read_image characterization test 
- Fix test_rehydrate_success race condition by using UUID for unique session IDs
- Add #[serial] attribute to prevent parallel execution conflicts
- Improve cleanup to remove entire session directory tree
- Add characterization test for resize_image_to_dimensions fallback behavior
  (documents fix from commit af8b849 for media type preservation)

1003386f7f Auto-resize large images (>=5MB) in read_image tool 
Images >= 5MB are now automatically resized to < 4.9MB using ImageMagick
before being sent to the LLM. This prevents API errors from oversized images.

- Uses iterative quality/scale reduction to find optimal size
- Converts to JPEG for better compression
- Shows original and resized size in terminal output (e.g., '6.2 MB → 4.1 MB (resized)')
- Falls back to original if ImageMagick fails or isn't available

3601cc0547 Enhance read_image tool with magic byte detection and multi-image support 
- Fix media type detection using magic bytes instead of file extension
  - Correctly identifies JPEG files with .png extension (and vice versa)
  - Supports PNG, JPEG, GIF, and WebP formats

- Add multi-image support with file_paths array parameter
  - Load multiple images in a single tool call
  - All images queued for LLM analysis

- Enhanced CLI output:
  - Inline image preview via iTerm2 imgcat protocol (height=5)
  - Dimmed info line showing: path | dimensions | media type | file size
  - Proper │ prefix alignment with tool output boxing
  - Human-readable file sizes (bytes, KB, MB)

- Add image dimension extraction from file headers
  - PNG, JPEG, GIF, WebP dimension parsing

- Add comprehensive tests for magic byte detection and dimensions
