The earlier "drop unsafe borderId read" fix (05ea0db) was based on the
assumption that Arcturus did not append a per-user borderId at the end
of each user record in RoomUsersComposer. That was true at the time —
but the Infostand Borders cherry-pick on the Arcturus side
(8f8f568, "feat: Infostand Borders") then added
`appendInt(getInfostandBorder())` at the end of EVERY user record
(single habbo, habbos collection, single bot=0, bots collection=0).
With the cherry-pick applied and the parser still skipping the read,
each user record left 4 unconsumed bytes on the wire. The NEXT
iteration's `id = wrapper.readInt()` then picked up the previous
user's borderId, the rest of the loop interpreted shifted bytes as
strings/ints, and the entire roster cascaded into corruption —
visible to the user as "I cannot see the other users in the room".
The bytesAvailable guard around this read is intentionally NOT
re-added: `bytesAvailable` is a boolean meaning "any bytes left in
the whole packet?", not "any bytes left for THIS user". With Arcturus
guaranteed to ship a borderId for every record (constant 0 for bots),
the read must be unconditional to stay wire-aligned.
