Update GitHub Copilot setup workflow with proper triggers and enhanced environment configuration

[Copilot]

Fixes the GitHub Copilot agent environment setup workflow to align with GitHub's best practices and documentation requirements.

Problem

The existing copilot-setup-steps.yml workflow was missing critical trigger events required by GitHub Copilot agents documentation and had dependencies that prevented it from running in environments without access to private Azure DevOps feeds.

Solution

Updated the workflow to include the required triggers and made it more accessible while enhancing the development environment setup:

Trigger Configuration

• Added push trigger for changes to the workflow file itself
• Added pull_request trigger for workflow file changes
• Maintained manual workflow_dispatch for on-demand execution

Environment Accessibility

• Removed private feed dependencies by adding /p:AccessToNugetFeed=false parameters
• Removed environment requirements that required special Azure DevOps credentials
• Maintained security with minimal contents: read permissions

Enhanced Development Tools

The workflow now installs a comprehensive set of development tools that Copilot agents commonly need:

# Entity Framework Core tools for database operations
dotnet tool install --global dotnet-ef

# ASP.NET Core scaffolding tools
dotnet tool install --global dotnet-aspnet-codegenerator

# NuGet CLI for package management
dotnet tool install --global nuget

Technology Stack Support

• .NET 9.0 SDK configured via global.json
• Docker Buildx for containerization workflows
• Node.js 20 with npm caching for frontend development
• NuGet package caching for improved build performance

Visibility Improvements

The workflow now generates detailed environment summaries including installed tools, framework versions, and project information, making it easier to debug and verify the setup.

Testing

• ✅ Validated YAML syntax
• ✅ Confirmed successful builds without private feed access
• ✅ Verified test execution works correctly
• ✅ Tested all development tools install properly

This change ensures GitHub Copilot agents have a properly configured, consistent development environment that matches the project's .NET 9.0 ASP.NET Core technology stack while following security best practices.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.hcaptcha.com

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
