fix: Vue slot rename — match font size, prevent error sound, fix reactivity

- Add .prevent on enter/escape keydown to suppress error beep
- Use text-[length:inherit] leading-[inherit] to match span font size
- Add right-click on connection dot to start rename
- Defer isRenaming=false to nextTick so label propagates before re-render
