Fill and review API documentation

[github-actions]

Fills the 4 remaining To be added. placeholders that surfaced after this run's stub regeneration, all on span-based overloads that mirror an existing string overload with fully-written docs.

What was filled (3 files, 4 members)

• SkiaSharpAPI/SkiaSharp/SKColor.xml — SKColor.Parse(ReadOnlySpan<char>) and SKColor.TryParse(ReadOnlySpan<char>, out SKColor) — mirrored the string overloads (same accepted formats, same return semantics).
• SkiaSharpAPI/SkiaSharp/SKFourByteTag.xml — SKFourByteTag.Parse(ReadOnlySpan<char>) — mirrored the string overload (up-to-4 ASCII chars, right-padded with spaces, longer truncated).
• SkiaSharpAPI/HarfBuzzSharp/Tag.xml — Tag.Parse(ReadOnlySpan<char>) — mirrored the ISO 15924 string overload.

What was reviewed

• The three touched type files (factual / examples / quality passes per references/reviewing.md). New prose is a direct restatement of the sibling string-overload docs already accepted in the repo, so no factual drift is introduced.
• Deterministic gate dotnet cake --target=docs-format-docs was run before and after; second run reports 0/5026 (0.0%) missing members and 0 finding(s), 0 error(s) across 406 type files.
