docs: hero and At a glance polish, fix vp-doc table layout

- Comparison matrix: animations, centering, VitePress table display override
- Home: centered hero tagline on locale homes; At a glance wrapper styles
- custom.css: .vp-doc .cmp-matrix__table restores display:table (home markdown is not under .main)
- Hero: Bundle Phobia button, npm downloads refresh; add HeroBundlePhobiaButton.vue
- skills.md: minor copy/version tweak
