Release v2.2.0: Add fluent API and simplified lifecycle management Latest

• Add Register() helper function for fluent component registration
• Add Run() helper function for simplified lifecycle execution
• Enhance lifecycle management with improved error handling
• Add comprehensive test coverage for new functionality
• Update example application with new API usage
• Improve component dependency management and startup order
• Add support for graceful shutdown hooks with WithShutdownHook()
• Enhance lifecycle status transitions and error propagation

BREAKING CHANGES:

• Lifecycle.Run() method signature changed:
• OLD: Run(ctx context.Context, readinessProbe func(err error)) func() error
• NEW: Run(ctx context.Context, readinessProbe func(err error)) error
• Lifecycle is now a Component without casting
• Added blocking Run() helper method with callback support
• Lifecycle no longer shuts down on signals by default (use WithShutdownHook() option)

Migration guide:

• Replace: waitFn := lc.Run(ctx, probe); err := waitFn()
• With: err := lc.Run(ctx, probe)
• Use goscade.Run() helper for blocking execution with callback
• Add WithShutdownHook() option if signal handling is needed
