v1.3.0

[1.3.0] - 2025-08-13

Added

• ui: add box_styled function which allows customising the border colour of a box
• ui: add button_id and button_id_styled functions which allow providing an
  unique internal id for the button, to support having multiple buttons with
  the same display text

Changed

• render: change render logic to only send redraw calls if the previous frame
  is different from the next, this largely reduces flickering in tmux though is
  still mostly a band-aid until proper diff-based rendering logic is
  implemented.

Fixed

• ui: fix issue with focusing when using align
• focus: fix issue when a button is removed from the view, it can still be focused
• focus: fix issue when cursor was not at end of line in an input field, progressing focus would cause it to reset focus
• layout: fix issue where focusable items in a grid were walked in reverse
