Run OpenRouter STT with Sapat in Daytona

[shuimaoiko]

/claim #13

Summary

• Adds a long-form Daytona guide for running OpenRouter speech-to-text through Sapat in a reproducible workspace.
• Adds a base64 audio transcription request definition, a first-time author profile, and an original SVG workflow diagram.
• Links the companion current-architecture Sapat provider implementation: Add OpenRouter STT provider nibzard/sapat#69
• Explains why this is distinct from the older closed OpenRouter attempt: OpenRouter now officially documents the dedicated /api/v1/audio/transcriptions endpoint.
