release: BeatDesign v0.2.0 - #10

Summary

• ships the local-first Studio, Canvas, Editor, Assets, Command Kernel, and 20-tool MCP workflow
• adds image/audio timeline support, browser MP4 export, Canvas-to-Editor continuation, local asset import, and provider discovery
• hardens Canvas/MCP revision synchronization, project Asset boundaries, local import validation, and idempotent command persistence
• refreshes the English and Chinese GitHub README with the approved BeatDesign cover

Verification

• typecheck passed
• 329 tests passed, 0 failed
• i18n passed: 683 English / 683 Chinese keys
• production build passed
• staged and branch secret scans passed
• real stdio MCP handshake and tool calls passed
• visible localhost smoke passed: Canvas prompt and Editor duration updated without refresh, then the QA fixture was restored through MCP

Current boundaries

• MP4 export is browser-driven, not headless MCP
• Editor snapshot is semantic, not a rendered pixel frame
• captions, transitions, speed controls, multiple timelines, and desktop packaging remain follow-up work

No BeatAPI SaaS Template files are included.
