Add 17 agent skills for .NET ecosystem and patterns

[Copilot]

Adds comprehensive agent skills covering functional programming, cloud-native development, CLI tooling, and modern .NET patterns.

Skills Added

Functional Programming & Type Safety

• Event-Driven Cheatsheet (CQRS, Event Sourcing, Sagas, Outbox pattern)
• Functional Programming Cheatsheet (monads, immutability, pattern matching)
• language-ext (Option, Either, Try, immutable collections)
• F# (language fundamentals, discriminated unions, computation expressions)
• Curryfy, Optional, Jflepp.Maybe (optional value handling libraries)
• Parse, Don't Validate (domain modeling with smart constructors)

Cloud & Infrastructure

• Azure Functions (serverless triggers, bindings, durable functions)
• Aspire Framework (distributed app orchestration, service discovery)
• Dotnet Web Apps (Minimal APIs, MVC, Razor Pages, Blazor)
• Dotnet Worker Services (background services, Windows/Linux hosting)

Developer Tools

• Reqnroll (BDD testing, Gherkin syntax)
• CliWrap (process execution, streaming, piping)
• Spectre.Console (terminal UI, tables, prompts)
• CommandLine Cheatsheet (System.CommandLine, argument parsing)

AI & Evaluation

• Evaluations (M.E.AI.Evaluations) (LLM output metrics, RAG evaluation)

Each skill follows the standard format with YAML frontmatter, installation instructions, code examples, and guidance section:
