Port the original #27 detected-language pipeline onto the verified PR #39 prerequisite while preserving the current-main conversation instrument and host continuity changes.
Keep voice selection server-side with no user selector or client voice field. Reuse 207c16ab only for its stricter exact-code trust boundary, omitting malformed or absent language so Piper defaults to Amy.
The composer routing chip showed bare AUTO/FAST/BALANCED/DEEP/MAXIMUM.
Relabel it to Automatic/Fast/Balanced/Deep/Maximum and align the
auto-route model option labels to Automatic · Fast/Balanced/Deep/Maximum

recognizable model name. Manual model names (Claude · Opus, etc.) are
unchanged. Update the image-build guard and its quality test to match.
