The OpenAI-compatible TTS endpoint accepts an `instructions` field, but it
was silently dropped at the HTTP->gRPC boundary: neither schema.TTSRequest
nor the gRPC TTSRequest proto carried it, so backends could only read such a
value from static YAML options (identical for every request). This blocked
per-line emotion/style and, for Qwen3-TTS VoiceDesign, limited a model config
to a single designed voice.
Plumb a generic per-request instruction string end to end, plus an optional
backend-specific params map:
- proto: add `optional string instructions` and `map<string,string> params`
to TTSRequest.
- schema: add Instructions (maps OpenAI `instructions`) and Params (LocalAI
extension) to schema.TTSRequest.
- core: thread both through ModelTTS/ModelTTSStream via a newTTSRequest helper
that attaches instructions only when non-empty (so backends can fall back to
YAML when unset); forward them from the /v1/audio/speech handler.
- qwen-tts: prefer the per-request instruction over the YAML `instruct` option
(used by both mode detection and generation) and merge per-request params.
- chatterbox: merge per-request params (coerced to float/int/bool) over YAML
options into generate() kwargs.
Fully backward compatible: empty instructions fall back to the YAML option and
backends that don't support style/voice instructions ignore the field.
