Merge branch 'dev' into abhi-9711/keyboard-shortcut-for-adding-block

Implements Ctrl+B/Cmd+B shortcut to open the blocks panel with full
keyboard navigation including arrow keys for selection, Enter to confirm,
and automatic focus management. Blocks can now be browsed, selected and
added entirely via keyboard.
