[Chore]: Update System.CommandLine package reference to 2.0.0-beta5

Motivation

The GenAIDBExplorer.Console project currently uses System.CommandLine version 2.0.0-beta4.22272.1, which is outdated and lacks the latest improvements and bug fixes. The new 2.0.0-beta5.25306.1 version provides:

• 32% smaller library size
• 20% smaller NativeAOT app size
• 12% startup time improvement
• 40% faster parsing compared to beta4
• Improved API consistency and coherence with .NET Framework design guidelines

Task Description

Update the PackageReference in src/GenAIDBExplorer/GenAIDBExplorer.Console/GenAIDBExplorer.Console.csproj from version 2.0.0-beta4.22272.1 to 2.0.0-beta5.25306.1.

This is the first step in the comprehensive System.CommandLine upgrade process and enables the subsequent code migration work.

Specific Changes:

• Locate the System.CommandLine PackageReference in GenAIDBExplorer.Console.csproj
• Update version from 2.0.0-beta4.22272.1 to 2.0.0-beta5.25306.1
• Verify the project can restore packages successfully

Acceptance Criteria

• PackageReference updated to System.CommandLine 2.0.0-beta5.25306.1
• Project builds successfully with dotnet build (compilation errors expected and acceptable at this stage)
• Package restore works without errors with dotnet restore
• No security vulnerabilities introduced by the new package version

Impact / Risk

• Expected Impact: This change will introduce compilation errors across all command handlers due to breaking API changes in System.CommandLine 2.0.0-beta5
• Risk Level: Low - This is only a package reference update; the compilation errors will be addressed in subsequent issues
• Dependencies: This change blocks all other System.CommandLine upgrade tasks
• Breaking Changes: Yes, requires follow-up issues to migrate code to new API patterns

Related Issues: This is part of the larger System.CommandLine upgrade effort as outlined in plan-upgrade-system-commandline-beta5.md
