Add CI/CD pipeline for Azure Functions deployment

[Copilot]

Implements automated build and release pipeline for deploying XPR MCP Server to Azure Functions.

Pipeline Architecture

Build Job:

• Node.js 20.x with npm caching
• Test execution (continue-on-error)
• Production dependency pruning
• Optimized artifact packaging (excludes dev files, research docs, tests)

Deploy Jobs:

• Production: Auto-deploys on main push
• Staging: Manual workflow dispatch
• Federated credential authentication (no stored secrets)
• Environment-specific Function App targeting

Configuration

.funcignore
Excludes from deployment: .git/, .github/, research/, agentic_dev/, test files, markdown docs

.github/workflows/azure-functions-deploy.yml

on:
  push:
    branches: [main, release/*]
  pull_request:
    branches: [main]
  workflow_dispatch:
    inputs:
      environment: [production, staging]

Setup Requirements

GitHub Secrets:

• AZURE_CLIENT_ID - Service principal client ID
• AZURE_TENANT_ID - Azure tenant ID
• AZURE_SUBSCRIPTION_ID - Subscription ID
• AZURE_FUNCTIONAPP_NAME - Function App name
• AZURE_FUNCTIONAPP_NAME_STAGING - (Optional) Staging Function App

Azure Resources:

• Function App (Node.js 20, Linux, Consumption plan)
• Service principal with contributor role
• Federated identity credentials for GitHub Actions

Documentation

• .github/CICD_SETUP.md - 5-minute setup guide
• PIPELINE_GUIDE.md - Comprehensive reference
• .github/DEPLOYMENT_STATUS.md - Deployment checklist

Security

• CodeQL scan: 0 vulnerabilities
• Workflow validation: actionlint passing
• Authentication: Federated credentials only
