New sharing UX, hotlink images and video, and a status bar that stays quiet until something is wrong

Every document and folder now has one stable share link whose role you can change any time, remote images and video render in live mode, and the status bar no longer narrates routine saves.

New

• Sharing UX redesigned, added fodler sharing. One stable URL per document or folder replaces the three per-mode links. Set Restricted or Anyone with the link, then Viewer, Commenter or Editor, and change it any time.
• Browse a shared folder from its link. Anyone with a folder link gets a page of its documents and subfolders, and opens each one from there.
• Hotlink images and video. A remote image URL used to render as a warning card. Now it shows inline, and <video src="https://..."> and <audio src> tags play with controls.

Improved

• A quieter status bar. The routine "Cloud autosave" and "Saved on this device" labels are gone. The bar now speaks only for Offline, Saving paused or Sync unavailable, and a reconnect under five seconds shows nothing.
• Saves recover on their own. A missed online event used to park sync until you reloaded. Now a 30-second check wakes it, stalled saves retry, and the bar stops claiming "Last synced just now" while stuck.
• Role changes apply live. When the owner changes your role on a shared document you have open, the change takes effect in place. The session used to pause with an authorization error.
• Type on a heading line safely. Home, a left-edge click or Up/Down at column zero used to land the caret on the hidden #, so typing produced d# Heading. It now snaps to the visible text.

Other improvements and fixes

• The share link is shown before your first copy, and copying works in Safari.
• Sharing a folder skips re-checking every document, and a refusal names those still saving.
• Already-saved documents no longer sit as pending after a reload.
• Selecting text no longer opens the floating menu while the formatting toolbar is showing.
• Text fields in the link, image and custom-action dialogs have their borders back.
• Offline, the sync popover says sync resumes automatically instead of offering Sync now.
• Reconnecting no longer re-uploads a whole document that once contained a deletion.
• Viewing a live shared document no longer keeps every incoming edit in memory.
