ดาวน์โหลด TermCanvas 0.27.3

- Dragging the left sidebar width no longer force-zooms the focused terminal back to fit-scale when the canvas is in plain (non zoom-focus) focus mode; the resize cleanup now consults the shared viewport focus state and only re-fits the viewport when the user is actually in zoom-focus mode
Changed
- The "zoomed out vs zoom-focused" flag previously kept as a local ref inside the keyboard shortcut hook is now lifted into a shared viewportFocusStore, so any surface that mutates the viewport (sidebar resize today, future panels tomorrow) reads the same source of truth instead of guessing the mode
