* Bump Electron to 43.7.8 to fix find-in-page looping
Find-in-page could loop when the host page contained iframes beside a
webview, so searches in the guest did not finish or wrap correctly.
Electron 43.7.8 includes the upstream fix (electron/electron#54199).
- Pin electron to 43.7.8 in package.json, pnpm-lock.yaml, and the
Node runtime pin.
- Raise the runtime floor in electron-runtime-floor.test.ts to 43.7.8.
- Add an Electron regression test that runs a find traversal in a
background window with host iframes before, after, and around a
webview, checking forward and backward matches wrap correctly.
* rm junk file
Electron 43.7.0 threw 'Invalid guestInstanceId' from <webview>'s
disconnectedCallback for a loaded guest (electron/electron#53989), so a
webview React removed and re-inserted kept a dead guest id: the tab went
blank, reload did nothing, and the destroyed listener never fired.
43.7.4 (electron/electron#54097) returns early when the guest is gone.
Raises the runtime floor test to 43.7.4 so a downgrade cannot re-ship it.
