Motivation
Enable Arduino IDE Linux builds for Arm64 systems; in particular Chromebook Linux environments running on Arm64 hardware.
Note that Arm64 Chromebook is the standard hardware platform for K-12 education.
Change description
Updated the Electron packaging flow to support Linux Arm64 AppImage and ZIP generation. The packaging script now prepares the required Linux packaging tools, ensures app-builder-bin is executable, adds the bundled 7zip binary to PATH, and forces maximum compression so AppImage creation uses a compression format supported by the Arm64 mksquashfs payload.
Added workspace dependency linking before packaging so electron-builder can correctly validate dependencies when Yarn workspaces have linked or hoisted packages outside the Electron app directory. This includes linking the local arduino-ide-extension workspace package and creating package-local links for hoisted production dependencies discovered by app-builder-bin.
Added a prebuild helper for the Electron app that builds arduino-ide-extension when the expected compiled extension entry point is missing, ensuring the Electron build has the extension artifacts it needs. Also pinned app-builder-bin through the root package resolutions to keep packaging behavior consistent.
Other information
The Linux-specific packaging changes are gated to Linux builds. The dependency-linking and extension prebuild safeguards run across platforms to keep workspace packaging consistent, so the primary compatibility risk is symlink behavior on Windows; existing CI should validate that path.
