STT billing feature IDs restructured, Pulse Pro pricing live

Billing feature IDs for Pulse and Pulse Pro have been restructured to namespace by model and transport. The old single-bucket IDs (feature-waves-stt, feature-waves-stt-pro, feature-waves-stt-pro-rpm) are retired; replacements are model + transport specific (for example feature-waves-stt-pulse-non-streaming, feature-waves-stt-pulse-streaming).

Per-minute customer rates on the Standard plan:

ModelTransportRate
PulseStreaming (WebSocket)$0.006 / min
PulseNon-streaming (HTTP)$0.0035 / min
Pulse ProNon-streaming (HTTP)$0.004 / min
Pulse ProStreamingNot available; endpoint returns 400

Standard plan defaults: 25 RPM per model on non-streaming, 100 concurrent WebSocket sessions. Enterprise: unlimited, configurable per-customer.

The Pulse Pro entitlement is gated by plan; Standard customers who need access can upgrade in the console or contact support.
