v9.39.0

Added

• Add Codex marketplace icon metadata and package the SVG asset for marketplace browsers (#385).
• Add session-scoped provider availability controls to /octo:model-config so users can disable exhausted providers such as Codex without uninstalling them (#386).

Fixed

• Surface the first provider stderr line in orchestrator logs when a provider command fails, while still preserving the full transcript in the result file (#404).
• Align OpenCode model catalog metadata with the current opencode/... namespace (#404).
• Replace low-risk ls/read shellcheck findings in orchestrate.sh with safer equivalents (#404).
