All services now validate required environment variables at startup, catching configuration errors before they cause runtime failures.

Improved

• Instant startup diagnostics for missing configuration. Strutter now validates every required environment variable the moment a service starts. If anything is missing or invalid, the service stops immediately and prints a single error listing all the problems at once, not just the first one. This replaces the previous behavior where a missing variable would only surface as a cryptic error minutes later when the affected code path ran for the first time.

Under the Hood

• Centralized schema-based validation runs before any request handling, covering both the main application and the background worker.
• Server-only variables are skipped during builds since secrets are not available at build time. Production-only variables (encryption keys, worker credentials) are enforced only when running in production.
• Validation covers both public client configuration and private server configuration through separate schemas, ensuring each surface area is checked independently.
