✨ Add debug flag for raw command output

[jordanpartridge]

Problem

When tests fail, users cannot see the raw Pest output that would help them debug the issue. The gate only shows processed/formatted output through the table interface.

Current Behavior

• Pest runs with --colors=never flag
• Output is processed and formatted into table
• Raw stderr and debugging context is lost

Expected Behavior

Add a --debug flag to show raw Pest output before formatting.

Proposed Implementation

File: app/Checks/TestRunner.php:46-50

Add debug output option:

$result = $this->processRunner->run(
    ['vendor/bin/pest', '--coverage', "--min={$this->coverageThreshold}", "--coverage-clover={$cloverPath}", '--colors=never'],
    $workingDirectory,
    timeout: 300,
);

// Add this after the run
if ($this->option('debug')) {
    echo "\n=== Raw Pest Output ===\n";
    echo $result->output;
    echo "\n=======================\n";
}

File: app/Commands/CertifyCommand.php:29

Add debug flag to signature:

protected $signature = 'certify
    {--coverage=80 : Minimum coverage threshold percentage}
    {--token= : GitHub token for Checks API}
    {--stop-on-failure : Stop at first failing check}
    {--compact : Show single-line output instead of verbose}
    {--debug : Show raw command output for debugging}';

Benefits

• Helps users debug complex test failures
• Provides full context that table formatting removes
• Non-breaking change (opt-in flag)
