opencodeSession: create image dir

Error message

opencodeSession: create image dir: %w

What it means

Wraps a failed os.MkdirAll of <workDir>/.cc-connect/images in opencodeSession.stageImages. It fires when the workDir (or the staging subdir) is not writable, so image attachments cannot be staged for the outgoing prompt.

Solutions

1. Fix write permissions on the project workDir
2. Remove any file occupying the .cc-connect name
3. Retry the image message after repair
