Require a server startup attempt.

The version probe also adds an entry to binaryPaths. This assertion can therefore pass if startOpenCodeServerProcess is never called. Record probe and startup paths separately and assert that both are present.

As per coding guidelines: “Backend behavior changes ship with focused tests for that behavior.”

Review comment at @packages/provider-opencode/src/server/driver.test.ts at line
107:
Update the test around `startOpenCodeServerProcess` to track version-probe and
server-startup paths separately, then assert that each is present so the test
verifies an actual startup attempt.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
