opencodeSession: save image: %w

Error message

opencodeSession: save image: %w

What it means

Fires while staging image attachments for an opencode prompt: the image directory could not be created under <workDir>/.cc-connect/images (permissions, read-only filesystem) or an individual image could not be written to disk. Wraps the underlying os error so the caller (Send) aborts the message send with a clear cause.
