Add context.Context support to more wrapper functions

[CybotTM]

Summary

Currently only TimeoutWithContext wrapper supports context propagation. Other wrappers could benefit from context awareness for better integration with modern Go patterns.

Current Context Support

Wrapper	Context Support	Notes
TimeoutWithContext	✅ Yes	Full context propagation
Timeout	❌ No	Abandonment model
Recover	❌ No	Could log context values
RetryWithBackoff	❌ No	Could cancel on context done
CircuitBreaker	❌ No	Could respect context
DelayIfStillRunning	❌ No	Could timeout on context
SkipIfStillRunning	❌ No	Could log context

Suggested Enhancements

RetryWithBackoffContext

func RetryWithBackoffContext(logger Logger, maxRetries int, ...) JobWrapper {
    return func(j Job) Job {
        return &retryContextJob{...}
    }
}

// Cancels retry loop when context is done
func (r *retryContextJob) RunWithContext(ctx context.Context) {
    for attempt := 1; ...; attempt++ {
        select {
        case <-ctx.Done():
            return // Stop retrying
        default:
            // Try execution
        }
    }
}

CircuitBreakerContext

Could skip execution when context is already cancelled.

Benefits

1. Better integration with HTTP server shutdown
2. More responsive cancellation
3. Consistent context propagation throughout chain
