Introduces code.nochebuena.dev/einherjar/telemetry — the observability bootstrap starter for the Einherjar framework. Absorbs the telemetry package from micro-lib, migrating from OpenCensus to OpenTelemetry SDK v1.42. Bootstrap functions (not lifecycle.Component — telemetry must be initialized before the launcher starts, and its shutdown must run after all components stop): - New(ctx, cfg) (func(context.Context) error, error) — production mode; exports traces, metrics, and logs via OTLP over gRPC to the configured endpoint; returns a shutdown function to be deferred in main() - NewConsole(ctx, logger, cfg) (func(context.Context) error, error) — development mode; writes structured telemetry to the provided logging.Logger; no network dependency; suitable for local development and CI Config (EINHERJAR_OTEL_* env vars): ServiceName(required), ServiceVersion(unknown), Environment(development), OTLPEndpoint(required for New), OTLPInsecure(false) ConsoleConfig (EINHERJAR_OTEL_* env vars): ServiceName(required), ServiceVersion(unknown), Environment(development) - identifiable.go: package-level Module variable (observability.Identifiable) for version identification — telemetry bootstraps before the launcher; not registered as a lifecycle component
