fix(node): one member holds a share of the node, sized past real use

128 peer sessions on the node, at most 64 per account (the hub names the
account with each offer; the node's own account is not counted). One account
plays at most half the stream slots, rounded up, and runs two subtitle
extractions at once. Frames after the handshake are 8 MiB (was 64), decoded
with per-container bounds, and a frame refused for either ends the session
instead of jamming its buffer (F-16).

Sized for the heaviest real member: twenty groups on one node, three devices
and a tab, up to 52 sessions. Measured: ~0.15 MiB and one fd per idle session.
