Refactor HttpClient polyfills: Uri overloads as primary, string overloads as delegates

[Copilot]

Previously, string overloads held the implementation and Uri overloads delegated via requestUri.ToString(). This is backwards — Uri is the richer, more precise type and should be primary.

Changes

• GetStreamAsync, GetByteArrayAsync, GetStringAsync: moved full implementation into the Uri overloads
• string overloads now delegate to their Uri counterparts via new Uri(requestUri)

// Uri overload — primary (contains logic)
public async Task<Stream> GetStreamAsync(Uri requestUri, CancellationToken cancellationToken = default) { ... }

// string overload — delegates
public async Task<Stream> GetStreamAsync(string requestUri, CancellationToken cancellationToken = default) =>
    await httpClient.GetStreamAsync(new Uri(requestUri), cancellationToken).ConfigureAwait(false);

Pull request overview

Refactors HttpClient polyfills so the Uri overloads contain the primary implementations and the string overloads delegate to them.

Changes:

• Moved GetStreamAsync, GetByteArrayAsync, and GetStringAsync implementation logic into the Uri overloads
• Updated string overloads to delegate to Uri overloads by constructing a Uri from the input string
• Updated docs links/comments to match the new primary overloads
