- Fixes apple#2065. - `startWatching()` returns before the watcher is ready to receive events, resulting in dropped events. Add readyEvents, an AsyncStream that yields once the watcher is actually active, so callers can await real readiness instead of guessing a sleep duration. - Prevent concurrent callers to startWatching(), as it does not support this mode of operation. - This fixes DirectoryWatcherTest's intermittent flakes.

Principally to address test flakes, but it does address startup races.
