Structured Logging

[CodeMaverick-143]

Plain text logs are difficult to parse and analyze in production environments.

Technical Implementation:

• Replace console.log with a structured logger.
• Output logs in JSON format by default in production.
• Include context: requestId, timestamp, level, pid.
• Support log levels: debug, info, warn, error.

---

Acceptance Criteria:

• Logs are output as valid JSON objects.
• Every log entry includes a unique request ID for tracing.
