When the OpenAI responses stream stalls (e.g. with github-copilot/
gpt-5.4), the error message "stream stalled while waiting for the
next event" is now recognized as a retryable transient error.
Two locations updated:
- packages/ai/src/utils/retry.ts: add "stream stall" to
TRANSIENT_MESSAGE_PATTERN (used by provider-level retry logic)
- packages/coding-agent/src/session/agent-session.ts: add
"stream stall" to #isRetryableErrorMessage() regex (used by
agent-session retry loop for both thrown errors and error
AssistantMessages)
Fixes#348
