fix: write RFL_DB.dat and rksys.dat atomically
WiiCompiled publishes a Linux AppImage since v0.2.26, but the recomp
integration was gated behind OperatingSystem.IsWindows(). The AppImage does
not speak the Windows setup's command-line contract (subcommands, its own
install-state.json without a setup version, no --check-products report), so
this adds a Linux implementation of IRecompInstallService that drives the
AppImage as it exists today, with no change required on the WiiCompiled side.

- RecompPlatform: platform gate and per-architecture release asset, shaped
  like the one in #371 so both merge cleanly. The three IsWindows() gates
  now use it. On a Linux Flatpak the option is shown disabled with an
  explanation instead of hidden.
- RecompSetupHostAcquirer: release lookup, download, chmod +x and --version
  verification, extracted verbatim from RecompInstallService and shared by
  both platform services.
- RecompLinuxInstallService: install --game for a new release, incremental
  install (no --game) for repairs and Retro Rewind updates, launch-retro,
  uninstall. Wheel Wizard keeps a copy of the AppImage and writes the v1
  install-state.json itself, so RecompInstallState, the payload policy and
  the status resolver are reused unchanged.
- RecompLinuxProductInspector: rebuilds the --check-products report from the
  AppImage's install-state.json and each product's local-build.json, hashing
  Retro Rewind's Code.pul to detect a stale build. Fails closed.
- RecompProcessRunner: SIGTERM for cooperative cancellation on Linux, and a
  one-time APPIMAGE_EXTRACT_AND_RUN retry when FUSE is unavailable.
- Config.toml, install locations and offered graphics APIs follow the
  AppImage's XDG layout on Linux.

An explicit "Products": null in the AppImage's install-state.json used to
overwrite the empty-list initializer on deserialization and make the product
inspection throw instead of reporting both products absent.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Review feedback: FUSE is nothing to rely on and the Wheel Wizard Flatpak
will run the AppImage inside its sandbox, so APPIMAGE_EXTRACT_AND_RUN=1 is
now set on every AppImage invocation (no FUSE attempt, no retry) and the
IsLinuxFlatpak gate, the disabled toggle and its helper text are gone.

Running unpacked also exposed that the AppImage runtime does not forward
SIGTERM to the setup it starts: signalling only the runtime left the setup
and its build orphaned. Cancellation now lists the whole process tree from
/proc first, signals every process in it, waits for the redirected streams
to close (which is when the setup's terminal result line has been read) and
only then falls back to SIGKILL. Verified against a real install: the setup
reports "cancelled" within 0.1 s and nothing is left running.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Review feedback: neither command builder should own a quoting scheme.
IRecompProcessRunner.RunAsync now takes the argument vector as separate
values and feeds ProcessStartInfo.ArgumentList, so both builders return
plain lists and the Windows and Linux Quote helpers are gone. Tests assert
the vectors instead of a joined string.

Also from the review of the runner:
- APPIMAGE_EXTRACT_AND_RUN is keyed on the .AppImage extension of the file
  being run, not on !IsWindows().
- The process tree is read through `ps -e -o pid=,ppid=` instead of /proc,
  which works the same on Linux and macOS (.NET exposes no parent id).
- The forced stop uses Process.Kill(entireProcessTree) for the root's own
  tree; descendants the AppImage runtime already orphaned are stopped
  through Process.GetProcessById(..).Kill(), since Kill(entireProcessTree)
  cannot see them once they are reparented. No more libc SIGKILL.

Verified on a real install: cancelling still makes the setup write its
"cancelled" result line and leaves nothing running.

The PR now targets dev, which carries the atomic save writes (#310) but
not yet main's recent commits this branch is built on (#362, #375, #378).
The one conflict was in MiiRepositoryService: main resolves the Mii
database path per frontend (#378) while dev writes it atomically (#310).
Both are kept: the atomic write now targets the resolved path, and the
directory creation dev dropped stays dropped since AtomicFileHelper
creates it.

Write the install state atomically.

WriteInstallState overwrites the JSON file in place. An interrupted write can leave invalid JSON, so the next update performs a full install --game rebuild instead of a repair. Use fileSystem.WriteAllBytesAtomic with the serialized UTF-8 JSON. Propagate its OperationResult; ignoring a write failure can report a successful install without recording its state.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Do not kill stale PIDs without identity validation

processIds is captured before SIGTERM and reused after the 10-second grace period. If a descendant exits and Linux reassigns its PID, Process.GetProcessById(processId) can resolve an unrelated process, and Kill() can terminate it without raising an exception. Re-enumerating ProcessTreeIdsAsync(process) alone is insufficient because orphaned descendants are no longer in that tree. Track each descendant with an identity-safe mechanism, such as a pidfd, before forcing termination.

Use a unique temporary path for each write.

When two WriteAllBytesAtomic calls target the same file, both calls use filePath + TempExtension. fileSystem.File.Create can overwrite the temporary bytes before the other call reaches File.Replace or File.Move. One call can save the wrong bytes, and the other call can fail.

Create a unique temporary file in the destination directory. Serialize writes per destination when callers require ordered updates. Add a concurrent two-writer regression test.

In `@WheelWizard/Helpers/AtomicFileHelper.cs` at line 45, Update
WriteAllBytesAtomic to create a unique temporary file in the destination
directory instead of deriving one from filePath + TempExtension, and ensure
cleanup and replacement use that path. Serialize concurrent writes targeting the
same destination when ordered updates are required, and add a concurrent
two-writer regression test covering byte integrity and completion.

Do not apply the portable user check in Flatpak.

IsLinuxDolphinConfigSplit() now sends every Flatpak user-folder validation through the split-config checks. Program.SetupWorkingDirectory() sets the working directory to the home directory, so _fileSystem.Directory.Exists("user") rejects every selected folder when an unrelated $HOME/user directory exists.

Guard that check in SettingsManager to match TryFindPortableUserFolderPath().

Proposed fix
-                if (_fileSystem.Directory.Exists("user"))
+                if (!EnvHelper.IsFlatpakSandboxed() && _fileSystem.Directory.Exists("user"))
                     return false;

SettingsManager’s IsLinuxDolphinConfigSplit() validation so Flatpak bypasses the
portable “user” directory check, matching TryFindPortableUserFolderPath();
retain split-config checks for non-Flatpak Linux configurations.
