v0.31.5

New MCP picture tools, camera blobs, and progress-bounded actions; --nv GPU on Jetson; launcher adjustments reworked.

Released on September 30, 2026

A launcher option no longer accepts a bare list of fragments; write several files as { fragments: ["a.json5", "b.json5"] }, the object form that also carries the option's own adjustments.
A fragment may adjust only the instances it deploys; move writes to other instances into the launcher's adjustments, at the top level or under the option that selects the fragment.
An MCP read of a topic with a representation returns its frame as a separate typed blob, removed from the JSON document and its schema; resources/list now reports the blob's image MIME type.

A topic with a jpeg representation can declare a picture tool that returns the latest frame as an image beside the rest of the message.
An action tool can set progress_timeout_ms instead of deadline_ms to bound a goal by its time without progress; it needs a feedback topic and no confirmation gate.
A cancelled action goal now returns the provider's result, in the tool error for a call or the status message for a task, and says why it was cancelled.

--nv containers on an NVIDIA Jetson now receive every driver library from the host's L4T container manifest, so CUDA and graphics run there as on desktop.

Unread action feedback buffers the newest messages, drops the oldest when full while always keeping the stream's end, and never blocks reading the goal's result.
