Add onboarding

Summary by CodeRabbit

  • New Features
    • Added a guided first-run setup for choosing Dolphin or WiiCompiled, configuring game and save-data options, and installing Retro Rewind in the background with progress and retry support.
    • Added support for managing, updating, importing data into, and removing managed Dolphin installations.
    • Existing Retro Rewind installations are moved into managed storage while preserving saves and user settings; unavailable drives can be retried later.
    • Added setup repair guidance and clearer startup progress messages.
  • Bug Fixes
    • Improved handling of unavailable folders and unreadable settings so existing setup choices are retained.
    • Updated WiiCompiled paths to follow current Dolphin and Retro Rewind locations.
  • Tests
    • Expanded coverage for setup, migration, and installation behavior across Windows, Linux, and macOS.

📝 Walkthrough

This change adds first-run onboarding, managed Dolphin installation, Retro Rewind migration and background installation, unavailable-path retention, Recomp path updates, startup maintenance, repair UI, and broad cross-platform test coverage.

Changes: Setup, migration, and managed services

Layer / File(s) Summary
Settings and unavailable paths
WheelWizard/Features/Settings/..., WheelWizard/Features/Dolphin/Paths/...
Settings retain rejected paths and expose unreadable-file state.
Retro Rewind migration
WheelWizard/Features/CustomDistributions/..., WheelWizard/Features/ApplicationLifecycle/...
Legacy installs use the managed root after migration. Unavailable folders defer migration. Failed renames use staged copying.
Managed Dolphin
WheelWizard/Features/DolphinInstaller/..., WheelWizard/Features/Settings/Views/WhWzSettings.axaml.cs
The application retrieves releases, installs or activates managed Dolphin, imports data, checks updates, and controls removal.
Recomp paths
WheelWizard/Features/Recomp/...
Recomp configuration receives current NAND and Retro Rewind paths. NAND choices update configuration after successful copies.
Onboarding and navigation
WheelWizard/Features/Onboarding/..., WheelWizard/Views/Shell/...
The shell opens onboarding when required. Onboarding configures Dolphin or WiiCompiled and locks navigation during setup.
Background installation and repair UI
WheelWizard/Features/CustomDistributions/RetroRewindBackgroundInstall.cs, WheelWizard/Views/Shell/ViewModels/HomeViewModel.cs, WheelWizard/Views/Shell/Views/HomePage.axaml
Background installation reports progress, retries failures, and uses unattended operations. Home displays installation state and setup repair actions.
Existing setup validation
WheelWizard.Test/Features/ExistingSetups/..., WheelWizard.Test/Features/CustomDistributions/...
Tests cover migration, onboarding gates, unavailable drives, staging recovery, managed installs, and repeated startup behavior.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 26e77

Onboarding, migration and managed Dolphin support look sound overall. One edge case remains: if adding managed Dolphin from settings fails for a user who had no Dolphin paths set, the settings keep pointing at the managed copy while it is treated as the user's own Dolphin. This is a small, low-effort fix that can be made before or soon after merge.

A rabbit watched the folders move,
Through staging paths they found their groove.
Dolphin learned a managed way,
While installs report each step of play.
Onboarding opened bright and clear,
And backup carrots stayed near.

onboarding do not count as a previous setup; use a persisted onboarding-started
setting in both checks. Set that marker when OnboardingPage opens and register
the corresponding boolean setting with the settings manager.

Review comments at @WheelWizard/Features/Settings/Types/Setting.cs:
- Around line 45-47: Update `Setting<T>.HasUnavailableValue` to rely on an
explicit presence flag set only when `KeepUnavailable` accepts a value, and
require `_retainsUnavailable` before reporting one. Clear the flag wherever
`Set` clears `UnavailableValue`, so value-type defaults are not mistaken for
retained unavailable values.
- Line 55: Update Setting.Set so validation failures leave UnavailableValue
unchanged, and clear it only after the new value is accepted. Preserve the
existing behavior of clearing it when the value already matches; if ApplyValue
fails with IOException or UnauthorizedAccessException, restore the previous
UnavailableValue along with the previous setting value.

🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Report copy progress only when the integer percentage changes.

DirectoryTransferService.MoveContents calls progress.Report once for each directory and once for each file. A Retro Rewind install has thousands of entries. With the current InlineProgress, every one of those calls runs t("onboarding.rr_moving", ...) and showStatus. The showStatus contract says it "may be called from any thread", so the splash handler probably posts each status to the UI thread. That can be thousands of dispatcher posts that show the same percentage. Send an update only when (int)(value * 100) is different from the last value sent.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

The rollback cannot restore an empty previous path.

The rollback calls SettingsService.Set with previousLocation and previousUserFolder. The comment in OnboardingService.Restore says that "the path validators reject an empty path". Assume the user had no Dolphin path or no user folder configured. In that case previousLocation or previousUserFolder is the default empty string. SettingsService.Set then returns false, and the code ignores the result. ManageDolphinButton does not depend on configured paths, so a user without paths can reach this flow.

After a failed install or import, the settings still point at the managed Dolphin, but ManagedDolphin.Deactivate() has already cleared the managed flag. The managed folder then looks like the user's own Dolphin. CanRemove can then hide the Remove action, and the error dialog suggests a full rollback that did not occur.

Reset the setting when the previous value is the default, as OnboardingService.Restore does. Alternatively, reuse IOnboardingService.CaptureFrontendSettings and RestoreFrontendSettings.
