Update x64 client for asteroid view distance quality profiles

Ship REM-Client 18b7816e2d900a23f2fc8628a76b93f2e4822a20 (Release|x64).
The existing REM view-distance control now selects Low, Medium, High or Ultra
and scales GPU reach, fallback drawing, distant impostors and background baking.
Ultra retains the previous drawing budgets and custom legacy reach.

Refresh the tested client binaries, default asteroid_quality=3 and exact source
provenance. The package, ZIP, REM-Mod and installed Lutris game use this build.

Validation: client/renderer builds, 400 range checks and four native flight
profiles; 11,141 runtime/data files matched at deployment and 252 runtime files
were reverified after committing source. Saves and settings remain unchanged.
