Tiptap's React wrapper initialises the menu element with
position:absolute, but computePosition needs position:fixed so
getOffsetParent returns the viewport instead of a positioned ancestor.
On the first show, coordinates were computed relative to the wrong
containing block, causing the menu to fly off-screen (negative coords).
Fix: set position:fixed in the onShow callback, which fires right
before updatePosition(), ensuring computePosition sees the correct
offset parent.

- 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

Base UI's DropdownMenu uses FloatingFocusManager which steals focus from
the editor (initialFocus + closeOnFocusOut), causing the BubbleMenu to
hide before dropdown item clicks can register. Popover supports
initialFocus={false} and finalFocus={false}, keeping editor focus intact
throughout the interaction.

The onMouseDown preventDefault on HeadingDropdown and ListDropdown
triggers was interfering with Base UI's menu event flow, causing:
- Dropdown appearing at top-left corner (positioning mismatch)
- Menu item clicks not applying formatting
The BubbleMenu plugin's own preventHide mechanism (capture-phase
mousedown listener) already handles preventing the menu from hiding
during dropdown interaction. Our extra preventDefault was redundant
and conflicting.

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

base-ui's Menu.Item only supports onClick, not onSelect (which is a
Radix UI API). onSelect was being silently ignored, causing heading
and list dropdown actions to never execute.

- Track child dropdown open state via ref to prevent blur handler from
hiding the menu while a heading/list dropdown is open
- Hide on ancestor scroll only (not sidebar/dropdown scroll)
- Hoist BubbleMenu options to module constant to avoid excessive plugin
updateOptions dispatches on every render
- Recover bubble menu after scroll via selectionUpdate

Add a floating toolbar that appears when text is selected in the editor.
Supports inline marks (bold/italic/strike/code), link editing with URL
auto-prefix, heading/list dropdowns, and blockquote toggle. Uses Tiptap's
BubbleMenu with fixed positioning and z-50 to escape overflow containers.
Hides on editor blur and ancestor scroll, recovers on new selection.
