Rebrand to GlitchCraft with IPv6 support

Changes:
- Renamed from "Text Corruptor" to "GlitchCraft"
- New slogan: "Artisanal text corruption, served fresh!"
- Updated server to support both IPv4 and IPv6 (dual-stack)
- Server now listens on all interfaces (::) instead of just localhost
- Updated all references in code and documentation

The new name reflects both the glitch aesthetic and the craftsmanship
of creating beautifully corrupted text, with a playful tone.
