otel_workmanager 0.1.0

OpenTelemetry instrumentation for `package:workmanager`. Wraps background-task registration and execution with task.* spans.

Changelog

0.1.0 - 2026-08-10

Added

• tracedWorkmanagerRegister<R>(...) — PRODUCER span around registerOneOffTask / registerPeriodicTask (called from the app's main isolate).
• tracedWorkmanagerExecute<R>({taskName, inputData, body}) — CONSUMER span wrapping the user's task body inside callbackDispatcher.executeTask. Runs in the background isolate; requires OTel.initialize() to have been called inside that isolate.
• Zone-scoped suppression (runWithoutWorkmanagerInstrumentation / async variant).
• WorkmanagerSemantics enum for the task.* attribute keys (no registry background-task convention exists yet).
• example/example.md covering both isolates.
• 5 tests.

Changed

• workmanager constraint widened to >=0.6.0 <0.11.0 (supports the latest 0.10.x; no workmanager API is called directly).
