0.0.1

• Initial release.
• ThermalUnicodeRenderer — renders Bangla, Arabic, Devanagari, or any other Unicode script ESC/POS printers can't natively handle, as bounded bitmaps sized to the printer's dot width.
• textLine — one (optionally word-wrapped) text block.
• row — one tabular row with ThermalCell(text, flex, align, bold), mirroring Expanded(flex: ...) inside a Row.
• divider — a full-width horizontal rule.
• Each render method has an ...Image() variant (raw image package img.Image) and a ...Png() variant (PNG bytes) for on-screen preview or further composition, alongside the plain ESC/POS-bytes form.
• Text is rendered through a real Text/Row widget mounted off-screen and captured via RenderRepaintBoundary, not a detached Canvas/ TextPainter — this avoids a class of Android bug (seen on some Impeller configurations) where manually-painted text renders blank while the identical text in a normal widget renders fine.
