/**
* <rstack-comment-bell> — Comment button with dropdown panel.
*
* Shows a chat-bubble icon in the header bar. Badge displays the count
* of unresolved comment pins on the current canvas. Clicking toggles a
* dropdown panel showing all comment threads, sorted by most recent
* message. Includes a "New Comment" button to enter pin-placement mode.
*
* Data source: `window.__communitySync?.doc?.commentPins`
* Listens for `comment-pins-changed` on `window` (re-dispatched by canvas).
* Polls every 5s as fallback (sync may appear after component mounts).
