Groundwork for the transcribe operation and for creating Studio when it is
first needed.
- Contracts: TranscribeInputSchema (artifact id, optional language code).
- transcribeChunks uploads audio chunks in order and stitches them into one
transcript on the original timeline; transcriptionChunkSeconds sizes
16 kHz mono WAV chunks below the server's upload limit; transcriptSummary
hands the bot the transcript, cut at a word.
- ensureStudioWhenMediaConfigured creates Studio once a media server
(generation or transcription) is configured. Local edits alone do not
count, because ffmpeg and image tools are present on most installs and a
specialist nobody asked for would appear for everyone.
