Problem

Image copying logic lived inside native chat, making it harder to reuse and leaving preview coverage incomplete.

Solution

Move image conversion and clipboard writing into a shared utility. Native chat now uses it, and tests cover copying from both thumbnails and image previews.

ELI5

Copying an image now uses one shared path, so it works the same whether the image is shown small or opened in a preview.

What Changed

• Added copyImageToClipboard to convert an image to PNG and write it to the local clipboard.
• Updated native chat image copying to use the shared utility.
• Added utility tests for successful copies and source, decode, and clipboard-write failures.
• Extended native chat context-menu coverage to thumbnail and preview surfaces.

Why

A single copy path avoids duplicated conversion and clipboard logic while ensuring images copied from previews behave like images copied from thumbnails.

📝 Walkthrough

The change adds a shared helper that converts an image blob to PNG and writes it to the clipboard as a data URL. Native chat image copying now uses this helper. Tests cover helper success and error cases, pending writes, and copying from thumbnail and preview surfaces.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 179dd

Native-chat image copying retains its clipboard payload format, and no actionable issue remains before merge.
