Hermes on ARM seeds linux-arm64-unpacked
Pull request 16124, merged into quattro, seeds the Hermes app on aarch64 into linux-arm64-unpacked, where an ARM update swaps the app in place. An existing ARM install seeded under linux-unpacked keeps that copy, and `--now` does not seed a second app.
On aarch64 the packaged app had been seeded into linux-unpacked, the directory used on x86_64. An ARM build uses linux-arm64-unpacked, so the first hermes update put the rebuilt app beside the seeded one. The menu launcher kept opening the old app, and the stale copy stayed on disk.
The pull request records that on an N1x, with a scratch home and the real hermes-desktop package, a fresh omarchy-install-hermes-cli --now seeded linux-arm64-unpacked, Hermes's own lookup resolved it, and the app launched from there. The launcher that opens the newest app in either directory is a separate package pull request.
