otel_logger 0.2.0

OpenTelemetry instrumentation for `package:logger`. A `LogOutput` that mirrors every log event into the OTel logs pipeline, carrying `trace_id` and `span_id` from the active span.

Changelog

0.2.0 - 2026-08-10

Changed

• Semantic conventions updated to the current OTel registry: deprecated attribute keys are no longer emitted (db.system -> db.system.name, db.operation -> db.operation.name, rpc.system -> rpc.system.name, with rpc.service folded into a fully-qualified rpc.method).
• Dependency floors raised to dartastic_opentelemetry ^1.1.0-beta.12 and dartastic_opentelemetry_api ^1.0.0-rc.1. The previous floors declared compatibility with API versions that predate the semconv enums this package uses and could not actually resolve-and-compile.
• repository URL corrected to the canonical Dartastic org casing so pub.dev repository verification succeeds.

Added

• OTelLogOutput extends LogOutput — drops into any Logger(...) construction and mirrors every event into the OpenTelemetry logs pipeline. Carries trace_id / span_id from Context.current so log lines inside a Tracer.startActiveSpan block are auto-correlated with the surrounding span.
• Maps logger.Level → OTel Severity: trace → TRACE, debug → DEBUG, info → INFO, warning → WARN, error → ERROR, fatal → FATAL. Deprecated verbose aliases TRACE and wtf aliases FATAL.
• LogEvent.error / LogEvent.stackTrace lift to OTel exception.type / exception.message / exception.stacktrace attributes. includeStackTrace: false opts out of the trace.
• runWithoutLoggerInstrumentation / async variant — zone-scoped suppression matching the rest of the OSS wrappers.
• 5 tests covering severity mapping, exception attribute attachment, opt-out, and suppression.
