dsh-whale-arcade: Mounting Five Browser Games in the Corner of a DeepSeek Harness Workspace

`dsh-whale-arcade` is a community-maintained DeepSeek Harness (DSH) plugin designed to meet entertainment needs during short waits in the Web workspace. The plugin is mounted on `shell.overlay` and provides a persistent whale launcher in the bottom-right corner, featuring five browser-native games: Whale Wave, Blue Whale Treasure, Whale Coast Run, Ocean Gomoku, and Tidebound Ruins. Its core advantage is that it "does not interrupt the Agent": the panel only occupies a corner of the workspace, automatically pauses while preserving state when closed, and supports resuming at any time. Three of the scored games save a Top 10 leaderboard in the current browser Origin, while the other two only retain progress during the mounted session.
