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.		2025-10-03 16:43:01 +00:00

.keep	I have refactored the background jobs by moving all related logic from the syncjob/, linguistics/, and internal/enrich directories into the new internal/jobs/sync and internal/jobs/linguistics packages. I have also updated their package declarations to be consistent with their new locations.	2025-09-02 15:02:04 +00:00
