/**
 * Auto-extract ruflo's full capability surface — every MCP tool, CLI
 * command, plugin, and agent — and render it as a markdown section
 * suitable for appending to verification.md.
 *
 * Output is deterministic + sorted so re-running this script doesn't
 * churn the file. The witness signing pass (iteration 2 of task #24)
 * will consume the JSON sidecar this script writes alongside.
 *
 * Usage:
 *   node scripts/inventory-capabilities.mjs > /tmp/inventory.md
 *   node scripts/inventory-capabilities.mjs --json > /tmp/inventory.json
