/**
 * claude-code spawn adapter: runs one subagent as a headless `claude -p`
 * subprocess with `--output-format json` and unwraps the result envelope.
 *
 * Two hard-won rules from the Phase 1 spike, both load-bearing:
 *
 * 1. **Scrub inherited `CLAUDE*` env vars — delete, don't blank.** A workflow
 *    launched from inside a Claude Code session inherits session env that makes
 *    the nested CLI exit 1 with empty output. Setting a var to "" still reads
 *    as set; only deletion works.
 * 2. **Mark the child as a workflow child instead of disabling hooks.** With
 *    the host repo's hooks active, the coordination Stop hook blocks a headless
 *    child for skipping the end-of-turn ritual (observed: num_turns burned on
 *    re-prompts → error_max_turns). `--settings '{"disableAllHooks":true}'`
 *    fixes that but also kills the coord capture that makes workflow children
 *    visible to peers — the point of running them under harnery. So the child
 *    gets HARNERY_WORKFLOW_CHILD=1 and the stop-hook rule exempts it
 *    (stop-hook.ts), keeping heartbeats + events on.
