/**
 * First coverage for `clampExternalCliBypassForOwner` (session-routes.ts), the
 * multi-user §6.3 gate that keeps a NON-GRANTED owner from launching an external
 * CLI with its safety switches off. It backs both `POST /api/sessions` and
 * `POST /api/quick-start` and, until pi was added, had no tests at all.
 *
 * The helper has two shapes and the difference is the whole point:
 *  - only-if-sent (codex, antigravity): an ABSENT config already spawns safe, so
 *    only a sent config needs its flag forced off.
 *  - MATERIALIZE (gemini, pi): the absent-config default is itself unsafe for a
 *    non-granted owner (gemini's builder defaults to `yolo`; pi's default is an
 *    interactive trust prompt the session user could just answer "yes" to), so
 *    the clamp has to CREATE a config.
