Package telemetry events (install, update, uninstall, download, details) are now queued in-memory and flushed as a single /_bulk NDJSON request instead of one HTTP request per event.
Flush is triggered by a new AbstractOperation.QueueDrained static event, which fires whenever the last running operation exits its queue. This means a burst of 30 package updates produces exactly one HTTP request, fired as soon as the last operation finishes — no fixed timer.
Added TelemetrySerializerContext.BulkTrimming (compact, non-indented JSON) required by the OpenSearch bulk API.
FlushPackageEventsAsync() is public for explicit calls from tests.
QueueDrained is wired in both the Avalonia and WinUI bootstrappers.
