Pack the GUI assets into app.asar while keeping the native generator executable available to spawn and saving preferences outside the read-only archive.

GUI version is 0.121.0, command-line version is 0.126.0, using Electron 45.2.3. This branch is based on current master, including the merged Apple settings support from #706.

• Enable ASAR in electron-builder and the Linux packager, unpacking app/**/*. Update macOS universal/archive paths and packaging scripts.
• Resolve the unpacked generator on every packaged platform; Linux packages now use their bundled generator. Keep the existing Linux development override.
• Save packaged-app preferences in Electron's user data directory. Read legacy settings as a fallback; development runs still use frontend/settings.json.
• Document the release version policy in README.md and AGENTS.md: every GUI version bump also increases the CLI version, including GUI-only releases. Add a PR check that rejects missing CLI bumps, decreasing versions and mismatched GUI lockfile versions.
• Add executable-path and preference tests, plus checks of archive contents and native generator execution in macOS, Windows and Linux packaging CI.

Validation: the release version check passes, with seven acceptance/rejection scenarios verified; the rebuilt CLI reports 0.126.0; all 13 GUI settings and packaging Node tests pass; local macOS arm64 packaging with Electron 45.2.3 succeeds; the code signature verifies; assets are packed and the unpacked generator runs --version, creates an osx project, and updates it successfully. Manual GUI/menu testing is pending. Universal macOS, Windows and Linux packages are left to CI.
