Motivation

After updating to System.CommandLine 2.0.0-beta5, the main entry point in Program.cs needs to be updated to use the new API patterns. The beta5 version introduces breaking changes that require:

• Replacing rootCommand.AddCommand() calls with rootCommand.Subcommands.Add() syntax
• Updating the main entry point to handle the new parsing and invocation separation
• Modernizing the command registration pattern

Task Description

Update src/GenAIDBExplorer/GenAIDBExplorer.Console/Program.cs to use the new System.CommandLine 2.0.0-beta5 API patterns for command registration and program entry point.

Specific Changes Required:

• Replace all rootCommand.AddCommand() calls with rootCommand.Subcommands.Add() syntax
• Update the main entry point to handle the new parsing and invocation separation
• Ensure the command registration follows the new mutable collections pattern
• Update any global options registration to use the new pattern

Files to Modify:

• src/GenAIDBExplorer/GenAIDBExplorer.Console/Program.cs

Acceptance Criteria

• All command registration uses rootCommand.Subcommands.Add() instead of rootCommand.AddCommand()
• Main entry point correctly uses new parsing and invocation pattern
• Global options (if any) are properly registered using the new API
• Project compiles without errors related to Program.cs
• Application starts and shows help correctly with --help option
• No regression in existing command-line interface behavior

Impact / Risk

• Dependencies: Requires completion of issue [Chore]: Update System.CommandLine package reference to 2.0.0-beta5 #15 (package reference update) first
• Risk Level: Medium - Changes to main entry point could affect all command execution
• Breaking Changes: Internal only - external CLI interface should remain the same
• Testing: Requires manual testing of application startup and help display

Related Issues:

• Depends on [Chore]: Update System.CommandLine package reference to 2.0.0-beta5 #15 (Update System.CommandLine package reference)
• Part of the larger System.CommandLine upgrade effort as outlined in plan-upgrade-system-commandline-beta5.md
