on Node 24, so index.js/electron-builder treat it as failed. Write
path.txt after running the installer.

electron's postinstall exits mid-extract on Node 24, leaving the binary
and path.txt missing. Replace it with a fully-awaited download+extract so
the binary is reliably present for the build and electron-builder.

Subject: [PATCH 10/16] ci: install electron via top-level-await helper for
 Node 24

A floating promise does not keep Node 24's event loop alive, so electron's
postinstall (and inline variants) exit before the binary extracts. Use a
helper script with top-level await so the process waits for completion.

Subject: [PATCH 11/16] ci: download electron via native fetch (Node 24
 @electron/get unsettles)

@electron/get's downloadArtifact promise never settles on Node 24 (exit 13,
unsettled top-level await), so the binary never installs. Download the
release zip with Node's native fetch + extract-zip instead.

Subject: [PATCH 12/16] ci: hold event loop open during electron install for
 Node 24

Node 24 exits as soon as the loop is momentarily empty, before electron's
download/extract promises settle. Keep a timer open until they do.

Subject: [PATCH 13/16] ci: install electron synchronously (curl+unzip) for
 Node 24

extract-zip hangs on Node 24 (never settles), like @electron/get. Do the
download+extract with synchronous shell tools so there is no async to stall.

electron 42 uses @electron/get@5 (native fetch) which installs cleanly on
Node 24, so electron's own postinstall works and the custom CI install
script is no longer needed.
