An Emacs client for DeepSeek Harness

Key features

• dsh-emacs is an Emacs frontend for DeepSeek Harness (dsh): it talks to a running dsh web service over plain HTTP/WebSocket and renders sessions, streaming replies, tool calls, thinking blocks and slash commands with an Emacs-native UI.
• Architecture — module layout, RPC API, event flow
• paste that whole printed URL (including ?token=…) into dsh-emacs-base-url — dsh-emacs reads the token from the query and strips it before building request paths.
• RPC protocol — complete dsh wire reference: methods, events, projections
