WebSocket integration tests fail in CI but pass locally

[rjcorwin]

Problem

Two WebSocket integration tests in the gateway package fail consistently in GitHub Actions CI but pass locally:

• should establish WebSocket connection with valid token
• should handle multiple participants in same topic

Symptoms

• Tests timeout waiting for WebSocket welcome messages
• Connection is successfully established (logs show "Participant joined topic")
• Welcome message is never received in CI environment
• Same tests pass without issues when run locally

Error Output

Error: Welcome message timeout
 ❯ Timeout._onTimeout tests/helpers/testUtils.ts:104:14

Attempted Solutions

1. Increased test timeouts from 5s → 10s → 20s
2. Increased helper function timeouts from 5s → 8s → 15s
3. Still fails even with 15-second timeouts

Current Workaround

Tests are currently skipped in PR #2 to unblock CI pipeline.

Investigation Needed

• Why do WebSocket messages fail to deliver in GitHub Actions?
• Is there a specific configuration needed for WebSocket tests in CI?
• Could this be related to how GitHub Actions handles network connections?

Environment

• Local: macOS, Node.js (tests pass)
• CI: GitHub Actions, Ubuntu (tests fail)
