Fix ChecksClient.logError() type safety (hasResponse on GuzzleException)

[jordanpartridge]

Context

app/GitHub/ChecksClient.php line 245 calls \$e->hasResponse() on a GuzzleException typed parameter. The hasResponse() method only exists on GuzzleHttp\Exception\RequestException, not on the GuzzleException interface.

The bug

private function logError(string \$method, GuzzleException \$e): void
{
    echo "::error::GitHub API error in {\$method}: {\$e->getMessage()}\n";

    if (\$e->hasResponse()) {  // <-- hasResponse() not on GuzzleException interface

Fix

Add an instanceof check:

private function logError(string \$method, GuzzleException \$e): void
{
    echo "::error::GitHub API error in {\$method}: {\$e->getMessage()}\n";

    if (\$e instanceof \GuzzleHttp\Exception\RequestException && \$e->hasResponse()) {

Acceptance

• PHPStan level 6+ passes without type errors on this method
• Existing ChecksClient tests still pass
