/**
 * pi-cursor-lite — Lightweight Cursor model Provider for Pi.
 *
 * Registers a "cursor-lite" provider that lets Pi users select Cursor models
 * via `/model`. Each request creates an independent one-shot Cursor Local Agent
 * run, streams back text/thinking, and disposes all temporary resources.
 *
 * Default mode is `plan` ("先规划"); set `PI_CURSOR_MODE=agent` at Pi process
 * startup to enable the `agent` execution mode.
 *
 * Requires a Cursor SDK API Key (set via `CURSOR_API_KEY` environment variable,
 * Pi `/login cursor-lite`, or `--api-key`). Does NOT reuse Cursor Desktop/CLI
 * login state.
