Drop the once-per-method dedup and its per-runner state: the client now
warns on every unbound notification (registering a binding, even a no-op
one, is the silence), and server-side inbound drops return to debug since
the peer is an arbitrary client and warning on its input floods the log.
Revert the ClientSession.send_notification widening: the 2026-07-28
transports do not agree on client-to-server custom notifications yet, so
the closed union stays the accurate type. Carve notifications/cancelled and
listen-owned acks out of the message_handler catch-all claim, add the
imports the notification example was missing, and note that a
json_response answer has no stream to carry request-scoped notifications.
Widen ClientSession.send_notification and ServerSession.send_notification
to accept any Notification subclass, mirroring send_request's open Request
arm, so extensions can emit their own methods without casts. Raise
dropped-notification logging from debug to a once-per-method warning that
names the remedy: on the client when no NotificationBinding observes the
method, on the server when a spec notification is not defined at the
negotiated version or a custom method has no registered handler (an
unserved spec notification stays at debug; repeat drops of a method log at
debug so a stream cannot flood the log). Document the message_handler
routing change and the binding channel in the migration guide, fix the
callbacks page's catch-all claim, and cover the vendor-notification round
trip with an interaction test, un-deferring its requirement.
* refactor: improve typing with memory stream type aliases
Move memory stream type definitions to models.py and use them throughout
the codebase for better type safety and maintainability.

Modified the websocket client to work with the new MessageFrame type,
preserving raw message text and properly extracting the root JSON-RPC
message when sending.
