doc: show GitHub stars and Discord members in the navbar

[kixelated]

Companion to moq-dev/moq.dev#142.

• Problem: The docs navbar had stock GitHub and Discord icons with no live counts, while moq.dev already shows hand-drawn icons plus star/member numbers.
• Approach: theme/Community.vue in nav-bar-content-after renders those icons with counts fetched in the browser and cached in localStorage for an hour. Hidden below 768px where the navbar is already full. GitHub and Discord stay in socialLinks so the mobile overlay still has them; custom.css hides those two stock icons in the desktop navbar so they do not duplicate Community.vue. The remaining socialLinks are @kixelated's X, Bluesky, and LinkedIn. Cache writes only a complete stars+members pair so a missing metric is retried.
• Impact: Docs site navbar only. No public library API or wire change.
• Alternatives: Mount Community.vue in nav-screen-content-after as well. That would keep the hand-drawn icons on mobile but mount the component twice and refetch unless the cache is shared.
• Follow-ups: None.

Discord's invite API echoes the origin in Access-Control-Allow-Origin and caches without Vary: Origin, so the fetch uses cache: "no-store" to avoid a stale moq.dev response failing CORS here.

just check passes.

Walkthrough

The documentation theme adds X, Bluesky, and LinkedIn social links. It mounts a new Community.vue component after the navbar content. The component fetches GitHub star and Discord member counts, validates the responses, caches complete results in localStorage for one hour, and formats the counts for display. Responsive styles hide the component below 768px. VitePress now generates /llms.txt, /llms-full.txt, and per-page Markdown twins while ignoring public/**.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 7029d

GitHub and Discord remain available in mobile navigation, with no actionable merge risk identified.

ITERATE

The navbar counts are a nice companion to moq.dev, and the Discord cache: \"no-store\" note is a real CORS fix. Complexity is low and worth it for the docs site.

Two holes before merge:

1. Below 768px Community.vue hides, and socialLinks no longer carry GitHub or Discord. Mobile nav loses both project community links and only keeps personal X/Bluesky/LinkedIn. Keep GH/Discord somewhere reachable on small viewports (stock socialLinks, or show the component without counts).
2. Caching when only one of stars/members succeeds locks a partial pair for an hour. Write the cache only when both are defined, or retry the missing one.

Fix those and this is an easy merge.
