Golang Observability

This is a production observability toolkit that treats the five signals (logs, metrics, traces, profiles, and RUM) as a complete system rather than isolated concerns. It pushes structured logging with slog, Prometheus histograms over summaries, OpenTelemetry tracing with context propagation, and environment-toggled profiling. The best part is the opinionated stance: a feature isn't done until it's observable, and it includes migration paths from legacy loggers plus links to awesome-prometheus-alerts for ready-made rules. It's explicit about cost tradeoffs and the high-cardinality label problem that kills Prometheus instances. Use this when you're instrumenting Go services for production and want guardrails that prevent the common mistakes.
