/**
 * The CLI's telemetry layer. Builds an OTLP HTTP exporter that ships spans
 * to {@link TRACES_URL} and metrics to {@link METRICS_URL}, attaching
 * {@link collectAttributes} as resource-level attributes so every signal
 * carries user/project/runtime context.
 *
 * If the user has opted out (via `DO_NOT_TRACK`, `NO_TRACK`,
 * `ALCHEMY_TELEMETRY_DISABLED`, or `~/.alchemy/telemetry-disabled`), this
 * resolves to {@link Layer.empty}. Effect's default `Tracer` is a no-op,
 * so all `withSpan`/`Effect.fn` instrumentation in core stays free.
