Address findings from 2 review agents on the room-nav draft indicator:
- Icon semantics (a11y): Icons.Message read as message activity and
collided with two existing bubble uses in the same row (call-chat
toggle, mark-unread), especially next to the unread badge. Replace it
with the composer's shared DraftDot (a small color.Success.Main dot),
so both draft surfaces share one visual language. Rendered as a
role="img" span with aria-label "Unsent draft" (reliably announced,
unlike a bare aria-labelled svg).
- Precise thread-key filter: hydration skipped any draftKey containing
'::', which would also skip an IPv6-literal server name in a roomId.
Match '::$' (thread root is an event id) so only real thread drafts are
skipped.
- Defensive hasMsgDraft: guard toPlainText so a corrupted/foreign draft
value can't throw during a nav render.
- Clear the draft atom on send: the send / scheduled-send handlers reset
the editor and localStorage but left the jotai draft atom set, so the
composer DraftIndicator could show a stale dot after sending a restored
draft. Add setMsgDraft([]) to both.
