Add a new HTTP endpoint end-to-end across the Go (Huma) backend and the Electron TS renderer. Use when the user asks to add a route, expose a new API, or wire a new request/response type from Go to TS. Covers the mandatory `Go struct → huma.Register → openapi → codegen → typed client` chain.

Add a Server-Sent Events (SSE) endpoint that stays inside the OpenAPI-driven contract. Use when the user wants streaming/long-lived push from Go to the renderer and WebSocket is not required. Covers registering `text/event-stream` in Huma, declaring a discriminated-union event schema, and writing the thin TS parser since `openapi-typescript` only types the stream body as `string`.

Add or modify a WebSocket frame type when WS is genuinely required (bidirectional, binary, or true full-duplex). This is the ONLY place where hand-written TS types are allowed in this project. Keeps the Go struct and TS interface in lock-step so the wire format never drifts.

Diagnose why `task dev` hot-restart isn't picking up Go changes (no sidecar respawn, stale endpoints, renderer hitting old port/token). Use when the user reports "I changed Go code but nothing happened", "the backend didn't reload", or "the watcher seems stuck".

Run the project's acceptance gate (`task verify`) and fix any typecheck, test, or lint failures it reports. Use before committing, before declaring a task done, or whenever the user asks to "verify", "run checks", or "make sure it passes".
