This PR enhances OpenTelemetry logging by adding comprehensive Vercel deployment context to improve observability and debugging in serverless environments. ### Changes - **Enhanced resource attributes**: Added function to parse `OTEL_RESOURCE_ATTRIBUTES` environment variable for additional context - **Vercel environment integration**: Automatically captures and includes Vercel-specific environment variables in telemetry data: - Deployment environment (`VERCEL_ENV`) - URL configurations (`VERCEL_URL`, `VERCEL_PROJECT_PRODUCTION_URL`, `VERCEL_BRANCH_URL`) - Deployment metadata (`VERCEL_REGION`, `VERCEL_DEPLOYMENT_ID`) - Git context (`VERCEL_GIT_COMMIT_SHA`, `VERCEL_GIT_COMMIT_MESSAGE`, `VERCEL_GIT_COMMIT_AUTHOR_NAME`) - Repository information (`VERCEL_GIT_REPO_SLUG`, `VERCEL_GIT_REPO_OWNER`, `VERCEL_GIT_PROVIDER`) - **Environment validation**: Extended `env.ts` schema to validate new Vercel environment variables - **Universal support**: Applied changes to both Node.js and Edge runtime instrumentation ### Impact Provides richer context in logs and traces, making it easier to: - Correlate issues with specific deployments and environments - Debug problems across different Vercel environments (development, preview, production) - Track performance and errors by Git commits and deployment metadata - Improve incident response with better deployment visibility This enhancement builds upon the existing OpenTelemetry setup while maintaining backward compatibility and following Vercel's environment variable conventions. <!-- START COPILOT CODING AGENT SUFFIX --> <!-- START COPILOT CODING AGENT TIPS --> --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.

The commit changes the logging approach by separating log metadata from human-readable messages across many files. The key changes are: - Adds descriptive message text to all log calls - Moves metadata into a separate object parameter - Consistently structures log keys and metadata fields - Improves error logging with serialized errors Subject: Add structured logging with human-readable messages Body: Enhances logging by separating structured metadata from human-readable message text. Makes logs more useful for both automated processing and manual review. Adds consistent error serialization and metadata structure.
