[FEATURE] Encina.Rollbar - Rollbar Error Monitoring Integration

[dlrivada]

Summary

Create Encina.Rollbar package for Rollbar error monitoring integration.

Motivation

Rollbar is a real-time error monitoring platform:

1. Real-Time Alerts: Instant error notifications
2. Intelligent Grouping: Automatic error deduplication
3. Person Tracking: Associate errors with users
4. Automation: Integrate with issue trackers

Proposed Solution

public static class RollbarExtensions
{
    public static IServiceCollection AddEncinaRollbar(
        this IServiceCollection services,
        Action<RollbarOptions> configure)
    {
        var options = new RollbarOptions();
        configure(options);
        
        services.AddRollbar(builder =>
        {
            builder.ConfigureRollbar(rollbarConfig =>
            {
                rollbarConfig.AccessToken = options.AccessToken;
                rollbarConfig.Environment = options.Environment;
            });
        });
        
        return services;
    }
}

Alternatives Considered

1. Use Sentry instead: Sentry has broader adoption and richer SDK, but Rollbar excels at intelligent error grouping and has a simpler pricing model for some use cases.

2. OpenTelemetry-only approach: Could rely solely on OpenTelemetry for error tracking, but dedicated error monitoring platforms provide better error analysis, deduplication, and alerting workflows.
