- 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

- Fix issue mention cards incorrectly triggering Link Hover Card
- Guard editor.view access in BubbleMenu against unmounted/destroyed
view Proxy (fixes desktop Inbox fast-switching crash)
- Use useEditorState for precise formatting state subscriptions in
BubbleMenu instead of relying on parent re-renders
- Add markdownTokenizer to FileCard for unambiguous !file[name](url)
roundtrip syntax (legacy CDN hostname matching kept for compat)
- Extract shared openLink/isMentionHref into utils/link-handler.ts

Replace Tiptap's BubbleMenu plugin with @floating-ui/react-dom for
all floating editor UI (formatting toolbar, link preview cards).
Architecture:
- useFloating({ strategy:"fixed" }) + createPortal(body) escapes
all overflow:hidden ancestors (Card component, scroll containers)
- autoUpdate + contextElement monitors all scroll ancestors for
repositioning; manual update() on transaction for virtual ref changes
- open prop resets isPositioned on visibility change (no stale-position
flash at 0,0)
- display:none for hiding (not return null which causes blur/focus
cycle, not visibility:hidden which leaves transition artifacts)
- No blur listener — portal DOM updates cause false editor blurs;
outside-click + scroll + resize + Escape handle all close cases
Bug fixes:
- BubbleMenu: remove all custom visibility hacks, let selection state
drive show/hide
- Link preview: new shared card (Copy + Open) for editable editor and
readonly markdown, portaled to body with fixed positioning
- TitleEditor: use JSON content format (not HTML interpolation that
loses < > characters)
- Blob URLs: strip from getMarkdown output during upload
- Markdown paste: check clipboard.files first to avoid intercepting
file paste events
- FileCard: escape HTML attributes in preprocessing
- Link extension: enable linkOnPaste, set defaultProtocol to https,
switch URL normalization to protocol blocklist (only block
javascript:/data:/vbscript:)
Dependencies: add @floating-ui/react-dom, remove @tiptap/extension-bubble-menu
