[Android Auto] Voice search mic only captures first word

Describe the bug
When using the mic button in the Android Auto search screen, only the first word of the spoken query is passed to the search function. For example saying "Journey Greatest Hits" only searches for "Journey", and "Heal the World" only searches for "Heal".

To Reproduce

1. Open SimpMusic in Android Auto
2. Tap the Search icon
3. Tap the mic button
4. Speak a multi-word song or artist name
5. Only the first word appears in the search box and results

Expected behavior
The full spoken phrase should be used as the search query.

Device info

• Samsung SM-F946B
• Android Auto mic button (blue listening bar appears correctly)

Additional context
The blue listening bar confirms Android Auto is capturing audio correctly. The truncation happens before the query reaches the app's onSearch callback. This may require Google media app certification for full multi-word voice search support in Android Auto.

Start at the Android Auto search screen and trace the query into the onSearch callback, checking where a multi-word voice result is truncated. Reproduce with phrases such as “Journey Greatest Hits” and verify that the complete phrase reaches the search results; also determine whether the limitation is imposed by Android Auto certification.
