fix(desktop): disable ProGuard optimization entirely — fixes kmp-tor crash

Disabling individual sub-passes (method/specialization/returntype,
method/marking/static) was not sufficient. The interaction between
multiple optimization passes causes IncompatibleClassChangeError in
kmp-tor's AsyncFs.of() at launch. Shrink (dead code removal) stays
ON for the size win; only optimize is disabled.
