Add CronCraft dependency injection registration

[teesofttech]

Summary

• add AddCronCraft() as an IServiceCollection extension
• support optional CronSettings configuration
• register options infrastructure for both configured and default usage
• register CronCraftService as a singleton
• document dependency injection setup in the repository and packaged READMEs
• add integration tests for singleton resolution, configuration, and fluent chaining

Why

Consumers currently need to register CronSettings and CronCraftService manually. This adds an idiomatic one-call registration API for ASP.NET Core and generic host applications while keeping direct, non-DI usage available.

Closes #9

Validation

• dotnet test CronCraft.Test/CronCraft.Test.csproj --no-restore — 39 tests passed
• dotnet build CronCraft.sln --no-restore — succeeded with 0 warnings and 0 errors

Summary by CodeRabbit

• New Features

  • CronCraft now includes optional dependency injection support, enabling convenient service registration and seamless integration with ASP.NET Core applications and other dependency injection containers.

• Tests

  • Added comprehensive unit tests validating dependency injection registration behavior, configuration application, singleton service registration, and service collection method chaining support.

• Documentation

  • Updated project and main documentation with complete dependency injection setup examples, configuration patterns, and practical guidance for integrating and injecting services.

📝 Walkthrough

Walkthrough

Adds an AddCronCraft extension method on IServiceCollection that registers CronSettings options and CronCraftService as a singleton, with an optional configuration delegate. Updates both project files with the required NuGet packages, adds three MSTest unit tests, and documents the new DI pattern in both READMEs.

Changes

AddCronCraft DI Registration

Layer / File(s)	Summary
AddCronCraft extension method and project dependency CronCraft/CronCraft.csproj, CronCraft/Extensions/ServiceCollectionExtensions.cs	Adds Microsoft.Extensions.DependencyInjection.Abstractions 9.0.6 to the main project, then creates ServiceCollectionExtensions with AddCronCraft that null-checks services, registers CronSettings options, conditionally applies the Action<CronSettings> delegate, registers CronCraftService as singleton, and returns the original collection.
Unit tests for AddCronCraft CronCraft.Test/CronCraft.Test.csproj, CronCraft.Test/ServiceCollectionExtensionsTest.cs	Adds Microsoft.Extensions.DependencyInjection 9.0.6 to the test project and introduces three MSTest methods validating singleton resolution, settings callback application with Convert output assertion, and fluent chaining identity.
README DI documentation README.md, CronCraft/README.md	Updates the "Why CronCraft" tagline to note DI is optional, adds an AddCronCraft feature bullet, and inserts a "Dependency Injection" subsection with registration and injection code examples in both READMEs.

Poem

🐰 A hop, a skip, a DI trick,
AddCronCraft wired up quick!
No more manual singleton woes,
Just inject wherever your cron job goes.
The rabbit typed—and chaining flows! ✨
