feat(Sky): Add LAND_SKIP_BUILTIN_EXTENSIONS to skip extension copy

Add support for the LAND_SKIP_BUILTIN_EXTENSIONS environment variable in CopyVSCode Step 13. When set to "true", the build process skips copying built-in VS Code extensions to the target directory. This enables the `debug-electron-minimal` and `release-electron-minimal` profiles (Atom J2) to produce bundles with zero built-in extensions on disk. Mountain's Scanner observes the same flag (Atom J3) and returns early for the built-in fallback paths at runtime, ensuring the runtime state matches the zero-on-disk configuration.

Also convert the PostHog telemetry request import from dynamic to top-of-file static binding, following the same pattern used for StripDanglingSourceMaps. Dynamic imports fail in `astro:build:done` because the Vite module runner has been closed by that stage.
