feat: big-suite terraform example + provider nodejs zip fix

- examples/big-suite: E-Commerce 10 functions, 6 layers, real depends_on
- provider: nodejs packages now wrapped in ESM zip (buildJSDeployZip)
- provider: loadPackageLiteral reads raw file, nodejs zip via source_dir
- all 10 functions verified working: python/node/ruby/go runtimes
