Create comprehensive GitHub Copilot instructions for CodeUI web application development

[Copilot]

This PR creates a comprehensive .github/copilot-instructions.md file that provides GitHub Copilot coding agents with complete guidance for working effectively in the CodeUI repository.

What this addresses

The CodeUI repository is currently in its initial state with only basic infrastructure files (README.md, LICENSE, .gitignore). The instructions provide a roadmap for developers working with this web-based AI CLI tools management application, covering everything from initial project bootstrap to advanced development workflows.

Key features of the instructions

Repository Assessment: Acknowledges the current empty state and provides guidance based on analysis of all project issues, correctly identifying this as a comprehensive web application (not a library) for managing AI CLI tools like Claude Code, Gemini, and Codex.

Technology Stack: Updated to reflect the actual project requirements:

• .NET 8.0 with C# 12 (validated for current environment)
• Blazor Server for the web application
• Key packages: CliWrap, Orleans, LibGit2Sharp, Pty.Net, Semantic Kernel, XTerm.js
• Terminal emulation, file system navigation, git operations, and session management

Validated Commands: Every command in the instructions has been thoroughly tested and verified to work correctly in the current environment:

• Solution and multi-project setup using standard .NET templates
• Blazor Server application creation with proper project references
• Build and test workflows with measured timing
• Package management for the specific technologies needed

Comprehensive Architecture Guidance: Complete guidance for:

• Bootstrapping an empty repository into a functional Blazor Server solution
• Project structure aligned with the 19 issues outlining application features
• Adding projects and managing dependencies for web application development
• Running builds, tests, and the Blazor Server application
• Integration patterns for CLI tools, terminal emulation, and distributed state management

Development Workflows: Based on the actual project requirements including terminal emulation with XTerm.js, Orleans grains for session management, git integration with LibGit2Sharp, and mobile-responsive design.

The instructions follow an imperative tone with firm directives and explicit "NEVER CANCEL" warnings for long-running operations, specifically tailored for web application development rather than library development.

Validation

All commands and workflows in the instructions have been tested end-to-end, including:

• Creating solutions with Blazor Server applications
• Building and testing multi-project solutions
• Project structure recommendations based on actual application requirements
• Technology stack validation for web application development

The instructions are designed to enable any developer to copy-paste commands and have them work reliably every time while building the comprehensive AI CLI tools management web application.

Fixes #20.

@copilot c#13 and .net 13, at his is not library this is the app. Review issues and my description

Updated the instructions to correctly reflect CodeUI as a comprehensive web application for AI CLI tools management, not a library. Analyzed all project issues and adjusted the technology stack to use .NET 8/C# 12 (available in environment), Blazor Server architecture, and all the technologies mentioned in the issues (CliWrap, Orleans, LibGit2Sharp, XTerm.js, etc.). The instructions now align with the project's actual purpose of providing a web UI for managing multiple AI CLI tools with terminal emulation and file system integration. Commit: 292107c

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:

• go.microsoft.com
  • Triggering command: dotnet new search aspire (dns block)

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)

The 'Repository Information' section is duplicated. Lines 205-210 and 212-218 contain nearly identical content and should be consolidated into a single section.
