Track Chatto 0.4.3

Chatto HQ is now serving 0.4.3. Per the version-tracks-Chatto policy,
chattolib bumps to match.

Only upstream .proto delta is a docstring change on
chatto.api.v1.ListRoomMembersRequest (default page size doc raised
from 20 to 250 — no wire change). buf/validate/validate.proto also
had comment-only tweaks. Client code and generated bindings are
unchanged in shape.

Live-verified against chat.chatto.run (0.4.3) with the RoboChatto
account: login, me(), list_rooms(), get_motd(), list_roles() all
decode correctly. ruff + mypy --strict + pytest all clean.

Also lands the scrapped tokio-leak-investigation bean
(chattolib-vel8): after measurement, RSS plateaus around 85-91 MiB
after ~2500 RPCs and dips back down — bounded tokio pool footprint,
not an unbounded leak.
