Two behaviour changes that bring the command line in line with established CAD workflow: 1. **Always-on keyboard capture.** The input was blurred whenever no command was running, so typed letters went nowhere until the user clicked into the field. Replace the blur with a re-focus on every command lifecycle transition (cmd_result.rs) and on viewport / tab / ribbon clicks (update.rs), focus the input at startup, and add a global key subscription that catches any unhandled character key or backspace and routes it into the buffer via two new messages (CommandAppendChar / CommandBackspace) — so the command line keeps accumulating keystrokes even if focus parks somewhere not focusable. Removes the unused blur_cmd_input helper. 2. **Space submits.** Typing a space at the end of the input now submits the buffer the same way Enter does. Only exception: an active command that's currently collecting free-form prose (TEXT / MTEXT / DDEDIT body, ATTDEF prompt / default value, INSERT attribute value, ATTEDIT cell). Those advertise the new `CadCommand::wants_text_with_spaces()` flag so the Space character reaches the buffer as a literal. Co-Authored-By: Claude Opus 4.7 <[email protected]>
