CI failures fixed in commit 3f9976a.

The issue was a failing test in test/ollama.test.js - the test "should start container and wait if not available" was missing stubs for docker commands (docker run, docker stop, docker rm) and had an incomplete fetch stub sequence for the model availability check.

Also fixed a flaky timing test in testSetupUtils.test.js that was expecting exactly 100ms but got 99ms due to timer imprecision - adjusted tolerance to 95ms.

All 547 tests now passing.
