isheng 2e30a5e628 fix: prevent /stop signal loss and empty provider credential corruption
Two deep bugs found through systematic analysis of the streaming API
call and fallback credential subsystems:

1. Interrupt signal loss (chat_completion_helpers.py):
   When the worker thread exits before the main thread's poll loop
   checks the interrupt flag (e.g. _call_anthropic() detects the flag
   and returns None), the while loop exits normally and the
   InterruptedError is never raised. /stop is silently swallowed.
   Fix: re-check _interrupt_requested after the while loop exits.

2. Empty provider bypasses credential guard (agent_runtime_helpers.py):
   recover_with_credential_pool() guards against cross-provider pool
   swaps with 'if current_provider and pool_provider and current !=
   pool_provider'.  When agent.provider is '' (valid unset state from
   agent_init.py:326), current_provider is falsy, the guard is skipped,
   and the pool swaps credentials onto an agent with empty provider.
   This is the root cause of the 'provider= model=' empty-string error.
   Fix: only skip the guard when pool_provider is empty (unscoped pool),
   not when agent provider is empty.
