Add ZipArchiveEntry extensions: ReadAllBytes/Text/Lines, WriteAllBytes/Text/Lines

[Copilot]

ZipArchiveEntry has no convenience API for reading/writing common data types — you must manually open the entry stream and wrap it each time.

Changes

• PowerKit/Extensions/ZipArchiveEntryExtensions.cs — New extension block on ZipArchiveEntry with sync and async variants:

  • ReadAllBytes / WriteAllBytes
  • ReadAllText / WriteAllText — optional Encoding parameter, defaults to UTF-8
  • ReadAllLines / WriteAllLines — returns/accepts string[] / IEnumerable<string>
  • All async variants accept CancellationToken

• PowerKit.Tests/ZipArchiveEntryExtensionsTests.cs — One test per method, exercising round-trip read/write against an in-memory ZipArchive

Example

using var archive = new ZipArchive(stream, ZipArchiveMode.Update);
var entry = archive.GetEntry("data.txt");

// Before: manual stream + reader boilerplate
// After:
var text = entry.ReadAllText();
entry.WriteAllLines(["line1", "line2", "line3"]);
var bytes = await entry.ReadAllBytesAsync(cancellationToken);

Pull request overview

Adds convenience extension methods for ZipArchiveEntry to simplify common read/write operations (bytes, text, lines) with sync + async variants, and introduces a corresponding test suite to validate round-trip behavior against in-memory ZIP archives.

Changes:

• Add ZipArchiveEntry extension methods: ReadAllBytes/Text/Lines + WriteAllBytes/Text/Lines with async counterparts and CancellationToken support.
• Add a new test file with one test per method, validating basic read/write round-trips via ZipArchive in Update mode.

@copilot please update PolyShim to v2.9.0, I've added polyfills that should fix some of the issues you've outlined.

Done in d729056. PolyShim updated to 2.9.0, which adds Net80/TextWriter.cs polyfilling FlushAsync(CancellationToken). All async write methods now use CT-accepting overloads directly — no more fallback plain-string variants needed.
