whale-on-desk: Mapping DSH Agent Status to a Pixel Whale Desktop Pet

`whale-on-desk` is a DSH plugin maintained by cookiesheep, designed to provide a pixel whale desktop pet for DeepSeek Harness, compatible with both the DSH web interface and desktop version. Positioned as an interactive component under the "everything is a plugin" framework, it does not replace Agent workflows but rather transforms status, approvals, and notifications into visible interactions, and is declared read-only, with no access to sessions or files. Its core capabilities include real-time reflection of Agent runs, outputs, tool calls, and success/failure states; alerting via the whale tapping on glass and amber pulses when approval is requested; and offering sound synthesis, position memory, a growth system, and a `whale_say` notification tool. Distinctive features encompass a full-screen aquarium mode, a workshop supporting AI-generated custom pets (requiring ffmpeg), and GIF-based functionality.
