Redesign docs with Apple-native theme; verify content; route CI to self-hosted runner-02

- VitePress: custom theme (SF system fonts, glass nav, soft surfaces, pill buttons,
  light/dark code blocks, refined feature cards, platform showcase + stat strip).
- Replace every emoji across docs and README with inline SVG icons.
- Verify and fix doc accuracy against actual scripts: JSON schema (category+pattern only),
  env-var configuration for json2*/import_* scripts, owasp2json CLI surface.
- Add public assets (logo.svg, favicon.svg, hero-shield.svg) and Shiki haproxy alias.
- Workflows default to self-hosted runner-02 with a configurable fallback to GitHub
  runners via the RUNS_ON repo variable.
