- Add GET /api/config endpoint exposing cdn_domain from CLOUDFRONT_DOMAIN
- Create packages/core/config/ zustand store, fetched at app startup
- Extract file card preprocessing to packages/ui/markdown/file-cards.ts
with isCdnUrl(url, cdnDomain) using exact hostname match
- Add file card support to packages/ui/markdown/Markdown.tsx (was missing)
- Remove hardcoded .copilothub.ai hostname check from file-card.tsx
- Fix LocalStorage.CdnDomain() to return hostname not full URL
- Always run preprocessFileCards regardless of cdnDomain availability
(!file syntax works without CDN domain, only legacy matching needs it)
- Use useConfigStore hook in common/markdown.tsx for reactive updates
