feat(v2-alpha): refactor binary simulator and introduce shared site layout
- Rewrite binary simulator with unified unsigned and two’s complement logic - Support dynamic bit widths from 4 to 64 with LSB-preserving resizing - Replace legacy unsigned-only scripts with a single maintainable implementation - Extract binary styles into dedicated CSS and add global site styling - Introduce shared header, footer, and base layout components - Migrate Binary page to BaseLayout and modular assets Signed-off-by: Alexander Lyall <alex@adcm.uk>
