Code Review: chore(deps): update dependency polyfill to 9.11.0

This is a Renovate Bot-generated dependency update PR, bumping Polyfill from 9.10.0 → 9.11.0.

Change Summary

The single-line change in TUnit.Core/TUnit.Core.targets updates the internal _TUnitPolyfillVersion MSBuild property:

- <_TUnitPolyfillVersion>9.10.0</_TUnitPolyfillVersion>
+ <_TUnitPolyfillVersion>9.11.0</_TUnitPolyfillVersion>

Assessment: LGTM ✓

This is a clean minor version bump with no concerns:

• Scope is minimal and correct — the change is isolated to the version property; the surrounding conditional logic for polyfill inclusion (netstandard2.0, netstandard2.1, .NETFramework) is untouched.
• Minor version — Polyfill 9.11.0 should be backwards-compatible per semver. The Polyfill library by SimonCropp is a source-only compile-time package (no runtime dependency), which means this update carries very low risk.
• No AOT / source-gen impact — Since Polyfill is a compile-time source generator, it has no effect on the TUnit engine's runtime or reflection paths, so the dual-mode requirement (source-gen + reflection) is unaffected.
• No snapshot test changes needed — The update does not alter any TUnit source generator outputs or public APIs.

No issues found. Safe to merge.
