[Feature]: Paste Image Support in Wave AI Panel

[Mostafa-Khairy0]

This feature adds support for pasting images directly into the Wave AI input panel.

When a user copies an image (e.g., from their clipboard or a screenshot) and pastes it into the input area, the image is automatically:

• Detected from the clipboard (image/* MIME type)
• Converted into a File object with a unique timestamp-based filename
• Validated for file type and size
• Added to the AI model via model.addFile()

This update improves the user experience by removing the need to manually upload images enabling faster and smoother AI-assisted workflows.

Walkthrough

This change refactors a frontend component to centralize file validation/upload via a new processFile(file) function, consolidates type and size checks, and adds paste-to-image support with handlePaste that converts clipboard images to File objects and processes them. handleFileChange now iterates over selected files, delegates to processFile, and clears the input afterward. handleUploadClick was shortened to a single invocation of the file input. Focus/blur logic was simplified and an inline focus method exposed on the input ref; handleFocus now calls model.requestWaveAIFocus() and handleBlur delegates to model.requestNodeFocus() when appropriate. Textarea receives an onPaste handler and textarea resizing is triggered in a useEffect on input and when the panel open state changes. No exported/public signatures were changed.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

• Verify processFile enforces allowed types and sizes, and that model.setError messages are appropriate for UI display
• Confirm handlePaste extracts image items from the clipboard consistently across browsers, infers extensions correctly, and constructs valid File objects
• Check focus/blur simplifications for regressions around requestWaveAIFocus() and focus retention when relatedTarget remains inside the panel
• Validate textarea resize useEffect dependencies and that resizeTextarea runs when input changes and when isPanelOpen toggles
• Ensure clearing the file input in handleFileChange and the one-line handleUploadClick work for multiple-file selections across target browsers

ah this looks like a good change, but the formatting differences make it a little harder to make sure there are no regressions. will try to review and make sure.

[Mostafa-Khairy0]

Appreciate the feedback! I can revert or isolate the formatting changes to make the review easier. Would you prefer I do that?

[Mostafa-Khairy0]

Just following up on this PR. Whenever you get a moment, I’d really appreciate a quick review so we can move forward. Thank you! @sawka

closing this. we had some very big updates to the paste code in the terminal to deal with file pasting, and i want to align the code to use those instead of duplicating them (termutil.ts)
