Add 10-minute timeout to test commands and disable e2e in merge pipeline

Test commands in run_project_tests now use wait-timeout to enforce a
600-second ceiling, preventing hung processes (e.g. Playwright with no
server) from blocking the merge pipeline indefinitely. Also disables
e2e tests in script/test until the merge workspace can run them safely.
