feat(website): add Black Myth inspired custom theme

[SoonIter]

Motivation

• Provide a complete, high-fidelity custom theme for the Rspress website with a refined Chinese aesthetic inspired by Black Myth: Wukong, replacing the homepage mockup with an original, game-like chapter-screen composition.
• Extend visual system beyond a single hero artwork to theme tokens, hero typography/actions, feature cards, documentation headings/blockquote/code blocks, responsive behavior and accessibility fallbacks.

Description

• Implement an original CSS-driven composition for the homepage hero in website/theme/components/HeroInteractive.tsx using layered elements (celestial wheel, mountain silhouettes, mist, staff, seal, chapter nodes) and localized labels for a Chinese chapter feel.
• Replace the previous Hero stylesheet with a purpose-built artistic module at website/theme/components/HeroInteractive.module.scss containing multi-layer gradients, masks, animations, depth shadows and reduced-motion fallbacks.
• Add a thematic token and layout stylesheet in website/theme/index.css that supplies light/dark tokens, parchment/ink/cinnabar/gold palette, typography defaults, nav/hero/button styles and site-wide visual extensions (backdrop texture, card borders, headings, blockquotes).
• Preserve the Rspress brand mark (logo) and implement responsive sizing and prefers-reduced-motion accessibility handling.

Testing

• Ran git diff --check and repository status checks, which passed with a clean index prior to committing the change.
• Ran code formatting with prettier during the workflow; formatting command completed with environment Node/pnpm warnings but no file errors reported.
• Attempted pnpm build:website but the build was blocked by pnpm supply-chain verification failing to reach the npm registry in this environment, so a full site build could not be completed.
• Attempted to create the PR metadata via the local make_pr MCP helper but the environment could not complete the helper call due to a missing mcp.server.fastmcp dependency, so the PR was not pushed by the helper (local commit was created: feat(website): add Black Myth inspired custom theme).
