teknium1 8cd4a96686 fix(browser): race condition in session creation can orphan cloud sessions ...

Two concurrent threads (e.g. parallel subagents) could both pass the
'task_id in _active_sessions' check, both create cloud sessions via
network calls, and then one would overwrite the other — leaking the
first cloud session.

Add double-check after the lock is re-acquired: if another thread
already created a session while we were doing the network call, use
the existing one instead of orphaning it.
