aiortc walked a message's fragments after each one arrived (n^2/2 steps
for a 1 MiB chunk) and acknowledged every packet. Measured on loopback,
400 MB to the CLI: 19 MB/s before, 39 after (49 by the node's count);
uploads from the CLI 25 -> 29 MB/s.

fix(node): stop aiortc's SCTP sender leaking bytes in flight2026-10-10T09:06:53ZChristophe Bessoncbesson@gmail.com2026-10-10T09:06:52Zurn:sha1:0ead6a321fbe3cf97e22f6fee348f68b09bd53a8
A chunk gap-acked then resent after T3 stayed counted for good; enough of
them and the node sent nothing more on that connection. The photo backup
stalled on it after a few dozen photos.
