Replace the inspect_image.enabled boolean with inspect_image.mode (auto|on|off, default auto). In auto the tool is registered only when the active model lacks native image input, so vision-capable models (e.g. kimi-code/k3) read images inline with their own capabilities instead of delegating to a separate vision model. on/off force registration regardless of model capability. - New utils/inspect-image-mode.ts resolves the effective state from the /vision session override, the persisted setting, and model capability - read tool re-evaluates the effective state per image read and re-renders its description, so it returns decoded image blocks again whenever inspect_image is hidden - /vision [on|off|auto|status] slash command (modeled on /computer) overrides the mode for the current session only - Tool set is reconciled on model switch with a status notice when inspect_image appears/disappears - Legacy inspect_image.enabled true/false migrates to mode on/off
