Add command to copy Etchvoid's last statement to input

Feature Request

Is your feature request related to a problem?

There's no way to programmatically access or copy the Etchvoid companion's last speech bubble statement into the input terminal. When Etchvoid says something interesting or relevant, users have to manually retype or remember it — there's no shortcut to pull it into the input box.

Describe the solution you'd like

A command (e.g. /etchvoid-last) or keybinding that copies Etchvoid's most recent speech bubble text into the current input field. This would allow users to:

• Quickly reference what Etchvoid said without retyping
• Use Etchvoid's statement as a prompt or conversation starter
• Paste it into the input for Claude to respond to directly

Describe alternatives you've considered

• Manually retyping the statement (error-prone, slow)
• Screenshotting and describing it (wasteful)

Additional context

Etchvoid is a delightful companion feature, and being able to interact with its statements more fluidly would make it feel more integrated into the workflow rather than a passive observer.
