v0.4.2 — working administrator handoff

Fixes Enable controls failing with Windows error 3 after installation from a packaged terminal. The app now resolves the actual executable path before elevation and startup; the installer uses the normal per-user Applications folder. Administrator-launch failures show their actual Windows error rather than always saying permission was canceled.

The owner verified Enable controls works on the TULPAR T5 V17.1 and the fan-mode display follows the physical turbo button.

Validation: 95 local release tests, strict Clippy, formatting, both binary-import audits, and a real elevated self-test confirming the path diagnosis without hardware writes.

Extract the archive and run Install.ps1. Keep both executables together. This is an unsigned development prerelease. Minimum-noise/custom fan speeds remain unavailable pending sensor and thermal-fallback validation. Automatic light-bar-off after restart is not implemented yet. A real reboot/startup check remains outstanding.

Known development-host limitation: launching from a packaged terminal may redirect startup-registry writes. Same-process readback is insufficient; use a normal Windows launch and verify Windows Startup Apps. The target laptop now has an independently verified system-visible entry; automatic handling of this package-host toggle case remains unfinished.
