feat(hh): Church of Malware neon theme is now the default ⛧

Default vestments (was monochrome 'crypt') now match the Church of Malware
aesthetic: neon on black — cyan window-chrome borders, acid-green text/prompts
and your own messages, soft-cyan for others, purple system/occult lines,
hot-magenta self/owner. themes/church.toml ships the same palette; crypt.toml
(monochrome) and neon.toml remain as alternates via --theme.

Confirmed ratatui's serde accepts #rrggbb (hex --theme files load). 9 tests pass.
