Hermes Agent ships Pretext layout skill

Hot take: this is less a generic productivity upgrade and more a sharp creative-coding capability drop. It makes Hermes Agent more useful for designers and frontend experimenters who care about text as a spatial material, not just content.

• –The new skill is built around `@chenglou/pretext`, so the differentiator is exact text measurement and layout, not visual styling alone.
• –The strongest use cases are obstacle-aware text flow, kinetic type, typographic games, and shrink-wrap UI where DOM reads would be brittle or slow.
• –The repo positioning is opinionated: single-file demos, canvas rendering, and intentional art direction instead of generic boilerplate.
• –This is especially relevant for browser-native creative work because it turns line breaks and grapheme positions into first-class geometry.
