Localization rework: rewrite docs/guide/localization/{index,how-it-works,
setup,troubleshooting}.md to describe Starlight-native i18n — locales mirror
the tree under docs/guide/<lang>/ (default English at root), the cms-jail
Astro deploy builds all locales, no external service in the live path.
Corrects the stale docs/public/ references (docs live in docs/guide/) and
demotes Crowdin to a clearly-labelled Future-plan note (not wired up today).
Slovenian batch 1 under docs/guide/sl/: navigable skeleton across every
section (top index + all six section indexes + the localization index) plus
two fully translated content pages (operate/terminal-capture,
architecture/control-plane-bridge). Literal commands/JSON/env-vars kept in
English; prose, frontmatter, and table headers translated. prettier-clean,
no real tailnet IPs. Content-heavy bodies (install/operate/architecture/
reference/roadmap) are batch 2, recommended after a native review of this set.
