NewConsole bootstraps the OTel SDK with three logz-backed exporters:
- Trace: WithSyncer, one log line per closed span (immediate, no batch)
- Metric: PeriodicReader (60s), flushed on shutdown
- OTel log: BatchProcessor, for third-party libs using OTel log API
ConsoleConfig requires only ServiceName — no OTLP endpoint needed.
Adds logz v1.0.1 as direct dependency; module tier bumped 1 → 2.
