/**
 * scripts/q.ts — sqlite3 CLI replacement for skill SQL invocations.
 *
 * Usage:
 *   pnpm exec tsx scripts/q.ts <db-path> "<sql>"
 *
 * Detects SELECT vs mutation on the first keyword. SELECT/WITH queries
 * print rows in sqlite3 CLI default ("list") format — pipe-separated,
 * no header — so existing skill text reads identically. Anything else
 * runs through db.exec() and prints nothing on success.
 *
 * Why this exists: setup/verify.ts:5 codifies that NanoClaw avoids
 * depending on the sqlite3 CLI binary; setup never installs or probes
 * for it. Skills that shell out to `sqlite3` therefore fail on hosts
 * where it isn't preinstalled (common on fresh Ubuntu — see #2191).
 * This wrapper preserves the skill-text shape (path then SQL string)
 * while routing through the better-sqlite3 dep that setup already
 * installs and verifies.
