google-labs-jules[bot] 3bcd8d08f5 feat: Implement observability stack
This commit introduces a comprehensive observability stack to the application, addressing a key objective from the TODO list.

The following features have been implemented:

- **Centralized Logging:** Replaced the existing custom logger with `zerolog` for structured, leveled, and performant logging. The logger is configured to output human-friendly console logs in development and JSON logs in production.

- **Distributed Tracing:** Integrated OpenTelemetry to provide distributed tracing capabilities. A new middleware has been added to create spans for all incoming HTTP requests, and the trace context is propagated.

- **Prometheus Metrics:** Added Prometheus metrics to monitor HTTP request latency and total request counts. A new `/metrics` endpoint is exposed on port 9090 to serve these metrics.

- **Request ID:** Implemented a middleware to add a unique request ID to every incoming request and response, improving traceability.

The new observability components are encapsulated in the `internal/observability` package, and the existing `internal/platform/log` package has been refactored to be a backward-compatible wrapper around the new logger.

The main application entry point (`cmd/api/main.go`) has been updated to initialize and gracefully shut down the new observability components.
