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.
Label each provider shutdown failure with its signal name (trace/metric/log).
Errors remain joined via errors.Join; individual causes still unwrappable.
Go directive bumped from 1.25 to 1.26. API committed as stable.
