Fill and review API documentation

[github-actions]

Fills all remaining To be added. placeholders detected by the docs-format-docs pass (20 members across 7 types, all in the SkiaSharp namespace) and reviews the affected files.

Filled (7 files)

• SkiaSharp/GRContext.xml — CheckAsyncWorkCompletion
• SkiaSharp/GRVkExtensions.xml — default constructor
• SkiaSharp/SKImage.xml — both RequestReadPixels overloads
• SkiaSharp/SKSurface.xml — both RequestReadPixels overloads
• SkiaSharp/SKImageRescaleGamma.xml — type + Src, Linear
• SkiaSharp/SKImageRescaleMode.xml — type + Nearest, Linear, RepeatedLinear, RepeatedCubic
• SkiaSharp/SKImageReadPixelsResult.xml — type + PlaneCount, GetPlaneData, GetPlaneRowBytes, CopyPlaneTo, ToArray, ToBitmap, ToImage, Dispose

All prose was written after reading the corresponding source in binding/SkiaSharp/ (SKImage.cs, SKSurface.cs, GRContext.cs, GRVkExtensions.cs, SKImageReadPixelsResult.cs, and the enum definitions in SkiaApi.generated.cs). Cross-references between the async-read API surface (RequestReadPixels ↔ SKImageReadPixelsResult ↔ SKImageRescaleGamma/Mode ↔ GRContext.CheckAsyncWorkCompletion) are wired up with <see cref>.

Reviewed (7 files)

Same file set. The three reviewers from references/reviewing.md were applied:

• A. Factual — accessor verbs, parameter roles, disposal semantics (SKImageReadPixelsResult valid only during the callback), and single-plane restrictions on ToImage/ToBitmap verified against source.
• B. Examples — no new code examples were added; no obsolete members introduced.
• C. Quality — .NET XML conventions, cross-links use T:/M:/P:/F: prefixes, no restatement of reference-table facts.

Findings summary

Deterministic lint before → after this run:

• Before: Documentation missing in 3/433 (0.7%) types and 20/5046 (0.4%) members, 0 findings, 0 errors.
• After: Documentation missing in 0/433 (0.0%) types and 0/5046 (0.0%) members, 0 findings, 0 errors.

No FINDING | lines were emitted by the deterministic checks and no additional CRITICAL correctness issues were identified in the reviewed files.
