This PR adds full Gerber support for
pcb_copper_text, including aperture config, vector text rendering, rotation, mirroring, and anchor alignment.A unified
renderVectorTextfunction is introduced and used for both silkscreen and copper layers.Knockout mode is supported via padded region drawing and polarity switching, enabling proper copper cutout text.
Two new snapshot tests validate normal copper text and knockout behavior across top and bottom layers.
