* Support dictation and image attachments in live terminal input mode
- Unify image attachment and voice dictation actions across both live
and buffered terminal input views using a shared action bar.
- Route completed dictations directly to the active PTY (matching
live keystroke semantics) when live mode is active, or append
them to the input field in buffered mode.
- Add live terminal status headers to indicate mic activity and
image upload progress.
- Include unit tests for the dictation routing logic.
