fix: permanent @swc/helpers MODULE_NOT_FOUND fix (#crash)

prepublish.mjs: explicitly copy @swc/helpers into standalone app/node_modules
before packaging. npm tarball will always include it.

postinstall.mjs: fallback copy of @swc/helpers from root node_modules into
app/node_modules/@swc/ when missing after npm install -g.

Fixes server crash after npm install -g omniroute.

+> ### Hotfix: Permanent @swc/helpers MODULE_NOT_FOUND Fix
+
+### 🐛 Bug Fixes
+
+- **`@swc/helpers` MODULE_NOT_FOUND crash on `npm install -g`** — Next.js standalone tracer does not always include `@swc/helpers` in `app/node_modules/`, causing an immediate server crash after install. Fixed in two layers:
+  - `scripts/prepublish.mjs` — now explicitly copies `@swc/helpers` from root `node_modules/` into the standalone `app/node_modules/` before packaging. The npm tarball will always include it from now on.
+  - `scripts/postinstall.mjs` — added a fallback that copies `@swc/helpers` from root into `app/node_modules/@swc/` if it's missing after install. Handles older versions and edge cases.
