fix(js): a CommonJS require and a module path import the file they name (#2263)

* fix(js): a CommonJS require and a module path import the file they name

A `require('./application')` was only a call, so a CommonJS file depended
on nothing at file level: Express's lib/express.js showed no imports and
impact missed the files it loads. Local require specifiers are now read
after extraction (both the wasm extractor and the kernel, including its
deferred-decode transport) as `imports` refs from the file, and a JS/TS
module path resolves to its file the way the runtime finds it —
extensions, index files, aliases — which also lands an extensionless
`import './polyfills'` on its file instead of its own import node.

* fix(js): read require imports inside each extractor, so kernel parity holds
