/**
 * One-shot runner for the ten MCP tools. Initializes the DB + fetch router the
 * same way the interactive shell does, but is searxng-free BY CONSTRUCTION: it
 * never calls `resolveSearchBackend` and never constructs a sidecar process.
 * The `search`/`fetch` tools route through the core provider (its own direct
 * adapters), but the research/agent/find_similar pipelines search the passed
 * engine instances directly — so we seed the same keyless direct engines the
 * MCP server uses (DuckDuckGo + Bing, no sidecar). Without these, one-shot
 * research/agent/find_similar would find zero web sources.
 *
 * Contract: RESULT → stdout, ALL logs → stderr. `--json` emits the tool's
 * MCP-shape JSON on stdout (exit 0), a failure exits 1, and under `--json` a
 * failure prints a JSON error object on stdout.
