// Package cursor is the Cursor Agent CLI llm.Provider.
//
// It shells out to the user's locally installed `cursor-agent` binary
// in non-interactive print mode (`-p`), reusing the existing Cursor
// sign-in — no API key in gortex's environment. `--output-format text`
// keeps stdout to the model's answer. The shared agentcli engine
// handles spawning, timeout, capture, and structured extraction.
