/**
* Headless Query — `gsd headless query`
*
* Single read-only command that returns the full project snapshot as JSON
* to stdout, without spawning an LLM session. Instant (~50ms).
*
* Output: { state, next, cost }
* state — deriveState() output (phase, milestones, progress, blockers)
* next — dry-run dispatch preview (what auto-mode would do next)
* cost — aggregated parallel worker costs
*
* Note: Extension modules are .ts files loaded via jiti (not compiled to .js).
* We use createJiti() here because this module is imported directly from cli.ts,
* bypassing the extension loader's jiti setup (#1137).
