 * The host → subprocess wire protocol. Commands travel as JSONL on the

 * This is the complete command set. Host behavior stays outside the
 * subprocess; the generic response frame only completes calls initiated by
 * the capsule-safe Axon facade.

 * Who asked for a command to run — "cognet" (the agent's own reasoning,
 * the default) or "host" (a developer typing into a live capsule).
 *
 * Owned by @arcforge/types like the rest of the capsule's session
 * vocabulary; re-exported here because the wire carries it. It rides the
 * wire rather than staying host-side because the subprocess is what emits
 * capsule:cmd:start, and one emission site carrying the truth beats two
 * sites that can disagree.
