What?

Closes #236

Adds two new image editing preset options: Remove item, Replace item

Why?

While you can always use the included textarea to make conversational edits to an image (including removing or replacing an item) it may be easier or feel more familiar to be able to select an item within the image to remove or replace. When using either of these new preset options, you will draw on top of the image (e.g. circle the item you want to edit) and then add an additional prompt (when replacing) to describe what you want to swap in.

How?

• Adds two new preset options that show in the AI Edit image mode: Remove item, Replace item
• When either is selected, render an image canvas that allows you to draw on top of the current image
• When finished, apply that drawing to the image and send that off to the LLM, along with a built-in prompt
• When replacing an item, also will show a textarea where you put in details about what you want the replacement to be which gets added to our built-in prompt
• Once the image is generated, the same existing flow is shown

Use of AI Tools

Generated and executed a plan using Claude Code running Opus 4.6. Did some final refinement myself and all testing
