Subject: [PATCH 1/2] fix(bot): fix TelegramChannel.__init__ NameError from
 undefined kwargs

TelegramChannel.__init__ references **kwargs in super().__init__() call,
but kwargs is not in the method signature. This causes a NameError when
the Telegram channel is instantiated, making it completely unusable.

Also fixes the type hint from undefined TelegramConfig to the correct
TelegramChannelConfig which is already imported.

Subject: [PATCH 2/2] fix(bot): skip empty content in assistant messages for
 Claude compatibility

When the LLM responds with only tool_calls and no text, content is None.
The expression `content or ""` produces an empty string, which Claude's
API rejects with 400 Bad Request ("text content blocks must be non-empty").

Only include the content field when it is non-empty.
