feat: add azure-container-apps skill for serverless container workloads 🤖🤖🤖

[krishna-sunkavalli]

What this adds

A new azure-container-apps skill in \skills/azure-container-apps/SKILL.md\ covering:

• Quick start — \�z containerapp up\ and step-by-step creation
• Container image sources — ACR with managed identity, Docker Hub
• Ingress — external/internal, custom domains
• Scaling rules — HTTP, TCP, custom KEDA (Service Bus, Queue Storage with managed identity)
• Revisions & traffic splitting — blue/green, canary deployments
• Jobs — scheduled (cron), manual, event-driven
• Secrets — inline values and Key Vault references
• Managed identity — system-assigned and user-assigned patterns
• Dapr integration — building blocks, component YAML, Tier 1/2 components, limitations
• Networking — VNet integration, service-to-service communication
• Health probes — liveness, readiness, startup
• Resource limits — CPU/memory matrix
• Monitoring — real-time logs and KQL queries
• End-to-end scenarios — multi-container microservice with Dapr, blue/green deploy, source-code deploy
• Troubleshooting — common issues and solutions

Why

Azure Container Apps is one of Azure's fastest-growing compute services for microservices, APIs, and event-driven workloads, yet the repo had zero coverage for it.
