fix(android): update JNI androidQuery bucket name to aw-watcher-android

[0xbrayo]

Closes ActivityWatch/aw-android#191

This fixes an issue introduced in #628 where the legacy '-test' suffix was dropped from buckets but not from the query.

Greptile Summary

This PR updates the Android JNI query bucket name. The main change is:

• androidQuery now queries aw-watcher-android instead of aw-watcher-android-test.

Confidence Score: 4/5

The Android query path can fail for existing users until the separate bucket migration has run.

• The new bucket prefix matches migrated watcher buckets.
• Datastores that still only contain aw-watcher-android-test... buckets no longer match this query.
• The function has no fallback or local migration before building the query.

Unmigrated Buckets Stop Querying

When androidQuery runs before migrateWatcherAndroidBucketNames has renamed existing aw-watcher-android-test... buckets, the new aw-watcher-android filter no longer matches the only stored Android watcher bucket. That makes the JNI query return an error JSON instead of the user's events until the separate migration entry point has run successfully.
