dsh-hud: DSH Web Floating Status Panel

dsh-hud is a community HUD plugin for the DeepSeek Harness Web interface: the input bar dashboard button opens a right-side floating panel, centrally displaying Git status and diffs, MCP services, Skills, model and token usage, session statistics, and account balance. Installable via `dsh plugin --profile web`, it is read-only and requires no build, making it suitable for quickly confirming repository and session status within the chat interface.
