fix(javascript): recover Electron APIs through default imports and optional calls (#1673)

`import electron from "electron"` bound the module with a leading `default`
export segment, so `electron.ipcMain.handle(...)`, `new
electron.BrowserWindow(...)` and destructuring from that binding matched no
Electron API. Electron's CommonJS exports define no `default` member, so the
segment can only denote the module object; drop it when classifying
Electron bindings.

The binding classifier already recorded optional-call roots, but the IPC,
context-bridge, utility-process and sender-validation visitors accepted only
plain calls. `ipcMain?.handle(...)`, `contextBridge?.exposeInMainWorld(...)`
and the common `event.senderFrame?.url.startsWith(...)` check were dropped
without a limitation.
