Assessment: Looks good ✓

This is a single-line, low-risk dependency bump managed by Renovate. The change is correct and appropriate.

What's new in Polyfill 10.3.0:

• ConfigureAwaitOptions polyfill for pre-net8.0 targets — relevant since TUnit multi-targets net8.0;net9.0;net10.0 and uses ValueTask/async heavily
• OS polyfill bug fix
• RequiresAssemblyFilesAttribute addition

Compatibility: The new ConfigureAwaitOptions polyfill is particularly relevant to TUnit's async-heavy codebase and its pre-net8.0 compatibility concerns. Nothing here conflicts with TUnit's AOT compatibility requirements or the Microsoft.Testing.Platform usage.

No concerns — auto-merge is appropriate for this minor update.
