Replaces three handfuls of custom code with upstream / static data:
- Per-app Steam launch options now declared via different-name/steam-
config-nix's `programs.steam.config.apps.<n>` instead of a custom
~70-line `apply_launch_options` Python function. The dropped writer
was racy: it edited localconfig.vdf without checking for a running
Steam, so any timer firing while Steam was open would lose its
changes on the next Steam shutdown. steam-config-nix's `closeSteam`
flag closes that race.
Also moves the GE-Proton compat-tool pin to declarative config —
one fewer manual click in Steam UI to remember.
- `mods.<>.launchOptions` option, the `launchOptionsData` aggregation,
and `LAUNCH_OPTIONS_DATA` are removed from desktop-game-mods.nix.
The module now does file-drops only; Steam config lives in its own
`programs.steam.config` namespace, where it belongs.
fh5-vkd3d-no-hvv (which existed only to set VKD3D_CONFIG) collapses
into the FH5 launchOptions block in hosts/yarn/default.nix.
- `unitConfig.X-ConfigHash` on game-mods.service is replaced with
`restartTriggers`. NixOS already emits `X-Restart-Triggers=<hash>`
on the unit; the workaround was redundant. The Type=oneshot,
RemainAfterExit=no semantics make `systemctl restart` re-run
ExecStart cleanly on hash change.
- The awk pipeline that patched OptiScaler's stock OptiScaler.ini at
build time is replaced with a hand-written hosts/yarn/optiscaler-
fh5-rdna3.ini containing only the keys we override (5 of them).
OptiScaler's Config::readString defaults missing keys to "auto"
(Config.cpp:1568), so a minimal file is sufficient. Side benefits:
one upstream-source dependency removed, a key-rename in upstream
becomes a behavior change rather than a silent awk-no-match.

- forza-trigger's three custom Python derivations (pydualsense,
hidapi-usb, fdp) factored out of default.nix into a sibling
python-packages.nix. Same logic, single-purpose file. Bumping a
version is now a one-place hash roll.
- pkgs.dualsensectl removed from the daemon's environment.system-
Packages. Single-shot writes from the CLI get clobbered by the BG
sendReport thread within ~4ms anyway, so the tool is only useful
with the daemon stopped — not worth the unconditional install.
Bring it in ad-hoc with `nix-shell -p dualsensectl`.
