Changelog

0.1.0-dev.1

Initial preview release.

• NavTelemetryObserver: a NavigatorObserver that emits structured NavEvents for push/pop/remove/replace/gesture/changeTop transitions.
• NavObserverConfig: severity filtering, sampling, per-minute rate limiting, popup/gesture inclusion toggles, and pluggable PII redaction (ArgumentRedactor / defaultRedactor).
• Sinks: NavEventSink abstraction with PrintSink, LoggingSink (package:logging), and CompositeSink fan-out.
• NavEvent.toJson() for JSON-encodable structured output.
• Zero DI coupling: optional loadConfigFromDI / loadSinkFromDI hooks on NavTelemetryObserver.observers(...).
