Electron Releases

Requested by John Kleinschmidt · Slack thread

Upgrades Node.js on main from v24.22.1 to v26.13.0. Of the 55 Node.js patches, 15 are removed because v26.13.0 already includes them, and the rest are adapted to upstream changes. This replaces #55418, which the roller closed and reset; review history is there.

Some changes need a closer look from reviewers. Node.js 26 allocates Buffer.allocUnsafe() memory through the isolate's ArrayBuffer allocator (nodejs/node#61480). Electron now gives the main process, utility process and ELECTRON_RUN_AS_NODE isolates their own allocator, so Buffers larger than 2 GiB keep working. ELECTRON_RUN_AS_NODE now honors --no-node-snapshot. Renderers and workers are started with --experimental-web-worker. The --experimental-transform-types switch is removed, because Node.js removed it, and the change is documented in the breaking-changes doc. The asar fs wrapper now covers Node.js 26's native write and copy jobs and its virtual file system. The trace_events, source-phase-import and process-timeout report tests are disabled for Electron-specific reasons, which are given in their commits.
