fix: make clipboard images pasteable in OpenClaude

Browse Source 
Images in the clipboard could fail to become pasted image attachments in OpenClaude. User-facing symptom: paste would detect that an image existed, but nothing would appear in the prompt, and bundled builds could also fail while converting BMP clipboard images into a format OpenClaude can send to the model.

Linux clipboard image paste had drifted between detection and extraction. checkImage accepted png/jpeg/jpg/gif/webp/bmp, but saveImage only tried image/png and image/bmp. When the clipboard advertised a JPEG, GIF, or WebP image, OpenClaude concluded that an image was present and then failed to write the temp screenshot file, so the paste path returned null and nothing was inserted into the prompt.

Bundled OpenClaude builds had a second failure mode. The build replaces image-processor-napi and sharp with explicit stub modules in bundled mode. getImageProcessor() treated those stubs as real processors, so BMP clipboard images reached sharp(imageBuffer).png() and then failed before they could be converted into a pasteable PNG for OpenClaude.

Keep the Linux clipboard commands generated from one MIME type list and reject __stub-marked image processors up front instead of failing in the middle of image paste.
