Retry transient Electron release downloads

[badcuban]

What changed

• retry Electron bootstrap downloads up to three times after thrown network failures
• retry electron-builder packaging only when its captured failure matches a transient network signature
• keep checksum, signing, build, and other non-network failures immediate
• add focused coverage for recovery, bounded exhaustion, and the exact release error signatures

Why

Nightly release run 31644702203 failed while electron-builder downloaded Electron with a socket hang up. A clean workflow retry then failed in the earlier Electron bootstrap download when GitHub closed the socket. Both paths previously made one external download attempt, so a transient connection reset could prevent an otherwise green release.
