* Replaces click-anywhere-on-bubble with a tiny ⋯ trigger in the meta row
that fades in on hover (always visible on touch devices). Outside-click
closes the menu, bubble gets a `menu-open` class so the trigger stays lit.
* Action menu gains Forward (any message) + Edit + Delete (own messages
only, delete is red). Reaction spinner + reply preview upgraded to handle
typed targets (attachment/invoice/location/alert) via summarizeForPreview.
* Pending-edit banner with ✎ icon mirrors the reply banner; Send flushes as
mesh.edit-message when pendingEdit is set.
* Forwarded bubbles render "↪ Forwarded from {orig_name}" header; tombstone
+ (edited) markers; pending-reply close button upsized (28px, red hover).
* Scroll + message-arrival watcher fires a debounced 400ms read receipt
with per-peer seq dedup so we never double-ack.
* Chat header: ⟲ rotate-prekeys button next to the shield badge; 📤 outbox
count when mesh.outbox reports queued messages. Blob-store test widget
removed and chat list now sorts by most-recent message timestamp.
