hwhkit-observability

Logging, tracing, and metrics initialization for hwhkit services.

This crate is normally pulled in transitively when you depend on hwhkit. Use it directly when you want to drive logging / OpenTelemetry initialization outside the standard bootstrap.

What this crate provides

• Default tracing layer (auto JSON in production, pretty in dev) based on tracing-subscriber.
• OpenTelemetry OTLP exporter (gRPC) under the otel feature.
• Client-side instrumentation wrappers under the optional otel-sqlx / otel-redis / otel-reqwest features so the resulting traces propagate across HTTP / DB / cache boundaries.
