/**
 * Staging a definition's instructions to a file, because herdr cannot carry them in argv.

 * Split out of `src/executors/run-herdr.ts` at the 400-line ceiling. A real seam rather than an arbitrary cut: this is
 * the one place that works around a **herdr encoding limit**, and it is the only part of the herdr path that
 * touches the filesystem. `run-herdr.ts` starts and reaps agents; this prepares one argument.

/**
 * Move a multi-line `--append-system-prompt` out of argv, because herdr cannot encode it.
 *
 * **Measured.** `herdr agent start` types the argv into the pane's shell, so a value containing newlines
 * is rejected outright: `invalid_agent_argument — agent arguments cannot be encoded safely for the target
 * shell`. A definition's `SKILL.md` body is always multi-line, so every `delegate({agent})` spawn would
 * fail on this path.
 *
 * pi accepts a **file path** there as readily as literal text (`resolvePromptInput` + `existsSync` in
 * `dist/core/resource-loader.js`), so the fix is to write the body to a temp file and pass its path — one
 * short, shell-safe argument.
 *
 * The split lives here rather than in `planSpawn` because the constraint is **herdr's**, not pi's: the
 * direct executor passes the same text inline with no trouble, and a plan builder that pre-emptively wrote
 * temp files for everybody would be paying one executor's tax on both paths.
