Unity Engine Critical Security Update for Terra Invicta

Build 0.4.90a addresses a critical security issue reported by Unity (Terra Invicta's game engine) earlier today.

Details: https://www.cve.org/CVERecord?id=CVE-2025-59489 All rollback builds have this issue, so we've taken them permanently offline. We are in the process of updating builds from other game platforms as well.

Update: The fix is also implemented in build 0.4.102 on our Beta/Validation/Experimental branches.
