Instrument WorkManager and Jobs

### Description

We could instrument Android's [WorkManager](https://developer.android.com/topic/libraries/architecture/workmanager) (and maybe other schedulers like [AlarmManager](https://developer.android.com/develop/background-work/services/alarms/schedule) or [JobDispatcher](https://developer.android.com/develop/background-work/background-tasks/persistent/migrate-from-legacy/firebase)) and power our `Queues` module.

Potential things we could capture:
* Job Status
* Job Start timestamp
* Job Duration
* Job Retries
* Job Constraints (network, etc)
* Job Frequency
* Call Stack

Android Studio's Jobs/Task inspector for inspiration:

Start by reading Android's WorkManager documentation and locating the repository's Queues module. Compare the proposed WorkManager integration with AlarmManager and JobDispatcher, then define which job signals are in scope and how they should be represented. The issue does not name implementation files or tests, and completion criteria are not yet specified.
