) :: {non_neg_integer(), non_neg_integer()}

Calculates new cursor position based on direction and movement amount. Ensures the new position is within the emulator bounds.

Parameters

• current_pos: Current {row, col} position
• direction: Direction to move (:up, :down, :left, :right)
• amount: Number of positions to move
• width: Emulator width for boundary checking
• height: Emulator height for boundary checking

Returns

New {row, col} position clamped to bounds
