feat(chat): copy generated images out of the conversation

Images an agent embeds in a reply render as plain <img> elements, so they
never got Obsidian's own image menu and there was no way to get the picture
out of the chat. Right-clicking one now offers "Copy image", which writes the
bitmap to the system clipboard so it can be pasted into any application or
another note.

PNG/JPEG go through Electron's nativeImage + clipboard.writeImage, matching
Obsidian's Live Preview behavior; other formats fall back to the async
Clipboard API. The embed's HTML now carries its vault path so the menu can
resolve the file, and the copy reports success or failure in a notice.
