[Bug] Linux tarball ships resources/terminal as 700, so the Go CLI never activates #869

Describe the bug
In ZenNotes-2.57.0-linux-x64.tar.gz, resources/terminal/ is drwx------ root:root; the files inside (zn, manifest.json, LICENSE) are world-readable. The AUR PKGBUILD copies it with cp -a, so the app, running as a normal user, cannot read manifest.json. zn keeps using the legacy Node CLI instead of Go zn 0.4.1.

To reproduce

1. Install zennotes-bin 2.57.0-1 from the AUR.
2. Open Settings → CLI.

Expected
zn is Go 0.4.1.

Actual
Settings → CLI shows "The bundled terminal manifest is invalid. Your existing CLI remains available." and zn --version prints zn v2.57.0. The message is misleading: prepare() returns null only for ENOENT, so the EACCES is reported as an invalid manifest.

Workaround
sudo chmod 755 /opt/zennotes-bin/resources/terminal, then restart the app. Settings → CLI then reports 0.4.1.
