Agent Canvas 1.39.0

Highlights

Automations dashboard filter by owner with a Service accounts option — The dashboard’s “Filter by creator” becomes “Filter by owner”. Me and Others match people only, and a Service accounts option lists automations that run as a service account. The option appears only when the instance reports service accounts enabled. See Managing automations.
Paper theme reads as aged newsprint with readable warnings — The Paper theme’s palette, code, diff, and terminal syntax colors, and its link role are reworked for contrast and a warm print feel. Warning text and automation health dots are now readable on every Paper surface.
Stop-hook feedback stays in the hook row — The SDK’s [Stop hook feedback] message is no longer repeated in the chat. The Hook: Stop blocked row still shows the reason and context when expanded.
Tighter message hover timestamps — The message hover timestamp sits closer to its message.

Chat resume visibility timestamps are interpreted as UTC.
Filtered sub-conversations are memoized in the websocket provider.
Chat is delivered over HTTP until the session socket is served.
The populated Event Key dropdown opens correctly.
Automations respect backend profile selection availability.
The setup guide starts the tour in an open dialog and ends it when that dialog closes, and drops an unanswered close question when the guide hides.
A missing event file no longer crashes the UI.

Bundled agent-server raised to 1.62.0, automation to 1.32.1, and @openhands/extensions to 0.42.0.
Dependency bumps and removal of merged PR artifacts.
