ci: skip electron test on Node 26.1+ extract-zip regression

Node 26.1.0 introduces an incompatibility with extract-zip 2.0.1
(used by electron's install.js): extraction silently terminates
after the first entry, leaving the prebuilt binary unextracted and
node_modules/electron/path.txt missing. Verified locally:

  - Node 26.0.0 + electron@34.0.0  -> install OK, require() OK
  - Node 26.1.0 + electron@34.0.0  -> install silently broken,
    require() throws 'Electron failed to install correctly'
  - Node 26.1.0 + electron@latest  -> install silently broken,
    require() throws ENOENT on path.txt

Both broken-install messages are caught in test/electron/run_test.js
and now produce a clear skip with exit code 0, plus the underlying
require() error is logged so the cause is visible in CI logs.

Also add --foreground-scripts to the electron install in npm test so
postinstall stdout/stderr is no longer hidden by npm's grouping.
