/**
 * Crow Bot Builder — Slice C approval-endpoint verification harness.
 *
 * Mounts the REAL bot-board-api router on a throwaway express server (ephemeral
 * port, stub auth) and exercises the proposed-skill GET/approve/reject endpoints
 * against the live crow.db with a NAMESPACED throwaway bot + a throwaway skill
 * name. Proves the security-critical behaviors without restarting the gateway:
 *   - GET lists staged proposals with guardrail flags
 *   - approve promotes operator-reviewed text → ~/.crow/skills + attaches to
 *     def.skills + def.tools.skills + clears staging; the promoted skill then
 *     resolves under BOTH runtimes (crowHome=~/.crow-mpa AND default)
 *   - approve refuses to overwrite an existing skill (409) and refuses symlinks
 *   - reject deletes the staged file
 *   - bad/traversal names are rejected (400)
 * Everything namespaced is torn down; production rows untouched.
 *
 * Run: CROW_DB_PATH=~/.crow-mpa/data/crow.db node scripts/pi-bots/slicec_api_e2e.mjs
