Honor the configured probe timeout before failing workspace discovery.

If activation takes 15 seconds and T3CODE_OPENCODE_PROBE_TIMEOUT_MS=60000, this branch still fails after 10 seconds. The outer snapshot deadline cannot extend this inner timeout. Previously, an unloaded directory could continue through the event-based scan wait after the ignored provider timeout.

Use the configured probe timeout here. Extend the regression test to cover activation that exceeds 10 seconds but completes within the configured timeout.

Review comment at @packages/provider-opencode/src/server/driver.ts at line 419:
Replace the hard-coded 10-second timeout on client.provider.list with the configured OpenCode probe timeout, retaining the existing 10-second fallback when no timeout is configured. Extend the regression test to verify workspace discovery succeeds when activation exceeds 10 seconds but completes within the configured timeout.
