* simplex-chat-python: split Client from Bot, add request/response API
Client is now the base class for SimpleX participants that talk TO
services (monitors, probes, automated participants). Bot extends Client
with server features (address, auto-accept, welcome, commands).
New methods on Client (inherited by Bot):
connect_to(link) idempotent contact handshake
send_and_wait(id, text) send a message and await the reply
events() async iterator over chat events
@on_message(contact_id=N) filter by sender in decorators
BotProfile renamed to Profile (alias kept). New ContactAlreadyExistsError
subclass for cleaner error handling.
* simplex-chat-python: narrow event payload type per @on_event tag
@client.on_event("contactConnected") now types the handler's event
parameter as CEvt.ContactConnected instead of the unnarrowed
CEvt.ChatEvent union — mirroring how @on_message narrows by
content_type.
The 50 overloads are generated by the Haskell codegen into _events.py
(as a Protocol class), so new events stay in sync automatically.
Client.on_event is exposed as a property typed as that Protocol; the
runtime implementation is unchanged.
