chore(release): prepare v0.4.0

[nao1215]

Added

• qrkit/render/png now exposes the same options-builder shape as qrkit/render/svg and qrkit/render/ascii: default_options(), with_module_size, with_margin, with_dark_color, with_light_color, with_background, and to_bit_array_with(qr, options). The existing to_bit_array(qr, scale:, margin:) is preserved as a thin wrapper over the new path. Colour fields accept #rgb, #rrggbb, and #rrggbbaa strings (the alpha component is read but currently honoured only via the with_background(False) toggle, which marks the light palette entry transparent through a tRNS chunk); unparseable strings keep the previous value rather than failing the call, mirroring the SVG renderer's lenient parsing. Closes the parity gap left by feat(render/ascii): expose with_margin (and/or options builder) like the SVG renderer #8. (feat(render/png): expose options builder like the SVG/ASCII renderers #28)
