fix: redesign landing page with Nous blue palette and cleaner layout

[austinpickett]

What does this PR do?

Redesigns the hermes-agent landing page to align with Nous Research branding. Replaces the gold/amber color scheme with the Nous blue palette, simplifies the page structure by condensing verbose sections into compact layouts, fixes terminal demo bugs, adds a Three.js noise overlay for visual texture, and converts the hero banner from a PNG to pure ASCII art.

• landingpage/style.css: Removed ~200 lines of dead CSS (accordion, tools-grid, tool-pill, platform-pill, skill-category, research-card, footer-card and their responsive overrides)
• landingpage/style.css: Added specs section styles (label/value rows), noise overlay canvas styles, and compact hero ASCII art styles
• landingpage/index.html: Replaced hero banner PNG with pure ANSI Shadow ASCII art rendered as a <pre> element
• landingpage/index.html: Condensed Tools/Platforms/Skills/Research accordion sections into a single spec-sheet layout with 5 label/value rows
• landingpage/index.html: Shortened all 6 feature card descriptions from multi-line paragraphs to single sentences
• landingpage/index.html: Simplified footer from 4-card grid to single text line: "Built by Nous Research · MIT License · 2026"

• landingpage/index.html: Updated nav logo from ⚕ symbol to Nous logo image with "Hermes Agent by Nous Research"

• landingpage/script.js: Ported NoiseOverlay from hermes-chat as vanilla JS with prefers-reduced-motion check

• landingpage/script.js: Removed emoji icons from terminal demo tool-call lines for consistent monospace alignment
• landingpage/script.js: Updated all color references from gold/amber to blue palette variables

How to Test

1. cd landingpage && npx serve -p 3000
2. Open http://localhost:3000 and verify the blue color scheme throughout
3. Scroll through all sections: hero ASCII art, install widget, feature cards, terminal demo, specs, footer
4. Check terminal demo plays correctly with cursor following content
5. Verify noise overlay renders (subtle grain texture visible on dark background)
6. Test mobile viewport — hamburger menu, responsive layout, ASCII art scaling
