fix(qqbot): add is_reconnect param to QQAdapter.connect for gateway reconnect compat

The base adapter's  signature was updated to include
, which the reconnect watcher passes as
 during reconnection. All other platform adapters were
updated, but QQAdapter was missed, causing:

    TypeError: QQAdapter.connect() got an unexpected keyword argument 'is_reconnect'

This leads to an infinite retry loop since every reconnect attempt fails
immediately with the same TypeError.

Fix: add  to QQAdapter.connect()'s signature.
QQBot has no server-side update queue, so the flag is accepted only for
interface conformance.

Test: new test_connect_accepts_is_reconnect_param verifies both
adapter.connect() and adapter.connect(is_reconnect=True) succeed without
raising.
