Run AssemblyAI transcription with Sapat in Daytona

[chinook1001]

/claim #13

Summary

• add a long-form Daytona guide for running Sapat with the new AssemblyAI provider in a reproducible workspace
• add an async speech transcription definition, first-time author profile, and original SVG workflow diagram
• link the companion Sapat implementation PR: Add AssemblyAI transcription provider nibzard/sapat#60

Why this is distinct

This submission targets AssemblyAI on Sapat's current provider-registry architecture. Current Sapat main has the merged 29-provider plugin refactor but no AssemblyAI provider; the old AssemblyAI PR targeted the pre-refactor CLI and was closed. This guide is paired with a current-architecture provider PR rather than another generic transcription article.
