Adds a built-in 'bunnny' skin preset with a hot-pink coquette palette:
- Hot pink (#FF3366) borders with Barbie-pink (#FF69B4) accents
- Lavender-blush (#FFF0F5) text on deep-plum (#2A0E1E) surfaces
- Coquette spinner verbs (sparkling, twirling, tying a little bow)
- Heart/sparkle/flower spinner faces (♡ ✧ ✿ ❀ ෆ)
- Heart (♡) prompt symbol and tool prefix
- (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧ kaomoji in welcome + help header
- Custom HERMES <3 banner_logo in pink gradient
- banner_hero of twin coquette bunnies holding paws, framed with
floating sparkles, hearts, and flowers to fill the banner width
Skin is cosmetic only — agent_name stays 'Hermes Agent'. Adds entry
to the skins.md docs table and ignores .venv/ in .gitignore.
