v2.1.0: Steam-proof loading — per-prefix Wine registry DllOverrides

Steam kept rewriting localconfig.vdf and dropping our WINEDLLOVERRIDES
LaunchOptions (account 919954036 lost it again -> user's session ran builtin
VERSION.dll, no unlocker, vanilla behavior).

scripts/prefix_override.py: writes version=native,builtin into
compatdata/1274570/pfx/user.reg [Software\Wine\DllOverrides]. Steam never
touches the prefix registry — override persists forever, zero env vars,
zero Launch Options. install.sh now applies registry (primary) + VDF (bonus).
Plain 'native' without fallback failed to boot; native,builtin verified.

Also verified this session: reverting UserHasItem/PlayerHasItem to pass-through
un-blocked real credit purchases (user bought an emote successfully); fabricator
injected remaining catalog ids on top of real ones (had=11 injected=52).
