v0.4.1 — Steam auto-prefix, remove/reinstall (preserves pilots + configs), payload cleanup

Install lifecycle management for the standalone + Steam installers.

Highlights

• Steam prefix auto-created: the Steam installer builds the Proton prefix itself (via the Steam Linux Runtime, Steam closed) — no manual "launch once, then re-run". Manual fallback if needed.
• --remove: restores the original (vanilla) game and, on Steam, clears the compat tool + launch options.
• --reinstall: --remove then reinstall using the version in the directory you run it from — the upgrade path. Reuses the ~6.6 GB XWAU zip paths + options recorded in <game-dir>/.xwau-install.json.
• Your pilots and settings are preserved across --remove/--reinstall: pilots (UserData/XWAU/Pilot/) and all config files are kept; only Hooks.ini is regenerated (mod-managed), and resolution/preset/ratio come back from the recorded options.
• Disk hygiene: the ~6.6 GB extracted payload scratch is deleted after a successful install (XWAU_KEEP_PAYLOADS=1 to keep).

Get it (no git needed)

curl -fL https://github.com/psoetens/xwau-linux/archive/refs/tags/v0.4.1.tar.gz | tar xz
cd xwau-linux-0.4.1

Upgrading from v0.3.0: the first --reinstall needs --xwau-full/--xwau-upd passed once (v0.3.0 installs predate the manifest); after that they're recorded.

Prebuilt Windows binaries are unchanged from v0.3.0 (carried forward so this tag is self-contained).
