Implement SRunner CLI with Terminal.GUI and System.CommandLine

[Copilot]

Bootstrap C# CLI application for managing service stacks with both command-line and interactive TUI modes.

Architecture

• src/Core: Business logic layer

  • ServiceRunner: Service lifecycle manager with case-insensitive name resolution and duplicate prevention
  • ServiceConfig: Validated configuration model with required Name/Command properties

• src/Cli: Presentation layer

  • Program.cs: System.CommandLine integration with --interactive flag
  • InteractiveUI.cs: Terminal.GUI implementation for service CRUD operations

Implementation Notes

System.CommandLine Version: Using 2.0.0-beta4 instead of requested RC version due to API surface changes in RC builds. Beta4 provides stable RootCommand, Option<T>, and SetHandler APIs.

Validation: Properties throw ArgumentException on empty/whitespace input. AddService throws InvalidOperationException on duplicates, handled gracefully in UI with error dialogs.

Usage

# Non-interactive mode
dotnet run --project src/Cli

# Terminal.GUI interface
dotnet run --project src/Cli -- --interactive

Documentation

.github/PROJECT_STRUCTURE.md provides architecture overview, development guidelines, and extension patterns for future contributors.

Original prompt

• A C# CLI project that use Terminal.GUI, latest dotnet 10 and System.CommandLine (2.0.0-rc.1.25451.107). It's calles SRunner.

• C# code should be in a folder src/ .

• Entry point to be In src/Cli.

• The cli ran with --interactive should launch an interactive CLI using Terminal.GUI.

• Code not linked to the user interface must be in src/Core.

• need basic AI structure in .github with ionstruction for Project structure
