[calumjs]

0. AI Development - Prompt & Model (include prompts/models used or N/A)

Prompt: Implement BytePlus (ByteDance) as a selectable provider and, when selected, replace transcription + transcript analysis with BytePlus-driven video processing before MCP execution.
Model: GPT-5 Codex

1. What triggered this change? (PBI link, Email Subject, conversation + reason, etc)

Conversation request to add a ByteDance/BytePlus experiment path so selecting ByteDance uses a BytePlus model for processing via MCP flow.

2. What was changed?

• Added �yteplus provider to shared LLM types/config.
• Added BytePlus provider config using BytePlus Ark OpenAI-compatible endpoint (https://ark.cn-beijing.volces.com/api/v3) and default model.
• Updated LLM config migration/storage to accept �yteplus.
• Updated onboarding/settings provider labels and typings to support BytePlus selection.
• Added video-frame summary prompt for visual processing.
• Updated process pipeline: when language provider is �yteplus, skip converting audio/transcribing/analyzing transcript and run frame-sampled visual analysis, then continue existing MCP execution and metadata flow.
