v0.2.2

Fixed

• Empty-composer and image submissions no longer fail with Client API: commands/execute rejected "images": the commands/execute face on a Session AgentContext is already Agent-scoped and accepts (line, images), not the root Remote form (agentId, line, images). Passing the Session id again shifted the command line into the validated images field. The command bridge now calls the scoped two-argument face and uses the target Session context for cross-Session retries.
