fix(update): Windows in-app update self-locked the uv venv

The menu/CLI update ran `uv tool install` in the foreground, but on
Windows this process is a child of the uv-venv python.exe that keeps
...\uv\tools\vortelio\Scripts open. uv then can't remove the old Scripts
("Access denied", os error 5) and leaves a corrupt, half-removed install
(uv tool list can't find the package). Route the Windows path through the
existing detached updater, which waits for this whole process tree to exit
before reinstalling, so nothing locks the venv. Unix keeps the foreground
path. Ship rebuilt 0.3.83 binary.
