Release v0.1.1

Added

• fable model tier: the Claude fable alias (most capable tier, above opus) is now selectable as the model for sandbox_agent / sandbox_research and the in-sandbox child variants when claude-code credentials are configured. Added to the pricing catalog so its usage counts toward cost reporting and the cap.
• media sandbox image: a new demesne-built image (FROM ubuntu:24.04) carrying ffmpeg, ImageMagick, libvips, and a broad audio toolbox (sox, lame, flac, opus-tools) for video/audio/image conversion. Wired through sandbox_script / sandbox_create / in-sandbox child variants exactly like the existing browser image; built lazily on the host on first use and content-hash cached via agentcommon.ImageBuilder.

Caveats

• This is a pre-1.0 release; APIs and the tool surface may change.
