/**
 * Regression guard for #2086 — ruvllm WASM auto-init via MCP tools.
 *
 * Reported by @seo-yas: every `ruvllm_*` MCP tool that touches the WASM
 * runtime requires `initRuvllmWasm()` to have run first, but no MCP tool
 * exposed that bootstrap call and `loadRuvllmWasm()` didn't trigger it.
 * Result: `ruvllm_status` reported `wasm.initialized=false` even after
 * calling `ruvllm_sona_create` / `ruvllm_microlora_create` / `ruvllm_hnsw_create`.
 *
 * Fix: `loadRuvllmWasm()` now calls `mod.initRuvllmWasm()` after import.
 * `ruvllm_status` deliberately keeps using the un-init loader so it can
 * report a non-initialized state for diagnostics.
 *
 * This smoke verifies:
 *   1. The `loadRuvllmWasm` helper exists AND calls `initRuvllmWasm`
 *      (regression catch — easy to delete the await in a refactor).
 *   2. The `ruvllm_status` handler does NOT call `initRuvllmWasm`
 *      (it must remain a pure diagnostic).
 *   3. The set of WASM-touching tools is exactly the expected list —
 *      adding a new ruvllm_* tool that talks to WASM without going
 *      through `loadRuvllmWasm()` is a regression of #2086.
 *
 * Run: `node scripts/smoke-ruvllm-wasm-auto-init.mjs`
