Start waiting for each watch restart before writing the file, then wait for a platform-scaled settling period before mutating it again. This gives watch mode time to process filesystem events and dependency reporting from the child process on slower CI machines.

Fixes intermittent failures in
test-watch-mode-restart-esm-loading-error.mjs.The test now starts waiting for the watch restart before writing the file and
waits for a platform-scaled settling period before the next mutation. This
reduces races with filesystem watch event delivery and dependency reporting
from the watched child process on slower CI machines.
