Improve console frame and input responsiveness

[ml6719]

Summary

• wake adaptive capture immediately after accepted keyboard or mouse input
• preserve coherent full-frame state for late and slow viewers while reducing repeated frame recomposition
• cache CIM method metadata and reuse synthetic mouse resolution across click sequences
• add capture/CIM/input-to-paint telemetry and a read-only Balanced-vs-Latency diagnostics benchmark
• raise only the Latency sample preset to 8 FPS and 900,000 bytes/sec; all policy, security, concurrency, resolution, input-size, and stable-release limits remain enforced
• prepare HyperVConsoleKit 0.6.0-preview.2 as an explicitly unvalidated prerelease

Validation

• dotnet restore HyperVConsoleKit.sln
• dotnet build HyperVConsoleKit.sln --configuration Release --no-restore (0 warnings, 0 errors)
• dotnet test tests\HyperVConsoleKit.Tests\HyperVConsoleKit.Tests.csproj --configuration Release --no-build (53/53 passed)
• dotnet pack ... produced HyperVConsoleKit.0.6.0-preview.2.nupkg and .snupkg
• self-contained win-x64 compatibility probe published
• build\Verify-Artifacts.ps1 passed
• build\Verify-CompatibilityMatrix.ps1 -AllowPending passed with the expected prerelease warning

Release caveat

No physical Hyper-V or browser latency benchmark has been run for this build. All seven physical compatibility entries are therefore recorded as pending for 0.6.0-preview.2; the earlier Server 2025 result is retained only as historical preview.1 evidence. This PR does not weaken the stable release gate.
