Squashed recreation of CommunityToolkit#862 on current main. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01E8bkzyS24p8CYDWLUPsaPC
Matches the tooling: .NET SDK 10.0.401, Uno.Sdk 7.0.0-dev.51, MSBuild.Sdk.Extras 3.0.44. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01E8bkzyS24p8CYDWLUPsaPC
DependencyObject is a class in Uno 7, so 'class, DependencyObject' fails with CS0450. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01E8bkzyS24p8CYDWLUPsaPC
Uno 7 annotates the parameter as non-nullable. Use the overload without easing instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01E8bkzyS24p8CYDWLUPsaPC

Bumps tooling to the matching Uno.WinUI 7.0.0-dev.2428, which returns IList<AutomationPeer> from ListViewBaseAutomationPeer.GetChildrenCore (unoplatform/uno#25141), so the TokenizingTextBoxAutomationPeer signature shim is no longer needed.

Uno 7 annotates the propertyType of DependencyProperty registration for trimming, so registering a property of type System.Type flags Type's own annotated members. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1DnHGnhiqjJz6RnRw
Uno 7 annotates ApiInformation's type name parameters for trimming, so the unqualified WinRT names fail with IL2122. XamlRoot and AccessibilitySettings.HighContrast always exist on WinUI 3, matching what Behaviors' ApiInformationHelper already does. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1DnHGnhiqjJz6RnRw
3.0.3 is built against Uno.WinUI 5, so Behavior types weren't WinUI 3 DependencyObjects on Uno 7. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1DnHGnhiqjJz6RnRw
Uno 7 implements RichEditBox. On Uno 5 (WinUI 2) RichEditBox is still a stub, so the control builds there but isn't functional. Also fixes IsXamlRootAvailable, whose WinAppSDK/UWP branches were swapped, and a nullable Window.Current dereference on Uno 5. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1DnHGnhiqjJz6RnRw
Builds the Uno.Sdk gallery heads against the local Converters, SettingsControls, Extensions and Triggers projects instead of the Uno 5 packages, and fixes NU1510 in net10.0 sample projects.

On Uno 5 (WinUI 2) iOS and macOS controls are UIViews, whose Window, Paste and Description members clash with RichSuggestBox (CS0120, CS0108, CS0114). RichEditBox is a stub there anyway. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1EDpoRrpP3hnDukwz
The job only built the Uno.Sdk head, so the SourceGenerators test step found no test assembly. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1EDpoRrpP3hnDukwz
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1EDpoRrpP3hnDukwz
Excluding Apple from WinUI 2 left the WinUI 2 iOS job with no TargetFrameworks for the project, which the solution generator still includes (restore failure). Resolve the UIView/NSObject member clashes instead: Description and Paste hide them with new, like SettingsCard.Description, and Window is fully qualified.

Uno.Sdk 7.0.0-dev.132 brings Uno.WinUI 7.0.0-dev.2556, which includes unoplatform/uno#25841 (no more [DynamicallyAccessedMembers] on DependencyProperty.Register). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TXMNu1EDpoRrpP3hnDukwz
Uno no longer annotates the propertyType/ownerType parameters of DependencyProperty.Register (unoplatform/uno#25841), matching WinUI, so the warnings these silenced are gone at the source.

🟡 Changes recommended
The target expansion enables RichSuggestBox on deferred, unvalidated Uno platforms despite its dependency on RichEditBox document APIs, so targets must remain Windows-only or be limited to validated platforms.

What changed in this PR
Migrates the toolkit’s WinUI 3 Uno builds to Uno.Sdk and Uno Platform 7, with updated platform targets, CI jobs, and compatibility fixes.
Changes:
- Updates SDK and behavior-package references and adds
win32targets while renaminglinuxgtktolinux. - Adds Uno.Sdk gallery builds on Windows and Linux using .NET 10 target frameworks.
- Adjusts focus handling, API checks, generic constraints, and animation calls for Uno 7; expands RichSuggestBox’s declared targets.

Looks good to me. Will defer to @Arlodotexe for final review for tooling changes too.

Should we depend on a dev build here? Is there no new stable release of this?

Moves the toolkit to the Uno.Sdk-based tooling on Uno Platform 7.0 (WinUI 3). This recreates #862 on Uno 7 instead of 6.x.
Important
Draft. It depends on the tooling PR CommunityToolkit/Tooling-Windows-Submodule#319 and on Uno 7 dev builds. The submodule pointer references the tooling branch on a fork and will move to the merged commit.
