Subject: [PATCH] fix(relay): add root nixpacks.toml to install scripts/ deps
 on Railway (#1760)

Railway builds from repo root (root_dir=""), so scripts/nixpacks.toml is
skipped. Root packages are installed via npm ci but scripts/package.json
deps (@anthropic-ai/sdk, fast-xml-parser, etc.) never land in
/app/node_modules, causing ERR_MODULE_NOT_FOUND at runtime.

Add a root nixpacks.toml that:
- Preserves existing scripts/nixpacks.toml settings (curl, NODE_OPTIONS)
- Adds `npm install --prefix scripts` to the build phase so all
  scripts/package.json deps are installed alongside root deps
