Some users may not want the console cleared. We may need to add the --preserveWatchOutput option.

Design Notes:
tsc --watchts.sys.watchDirectory. However, it was unclear whether this API would be provided in ts-go, so it was not adopted.runCMKInWatchModefunction.runCMKInWatchModedelegates most processing toProject.Projectis used by both therunCMKfunction for normal mode and therunCMKInWatchModefunction for watch mode. It implements the common logic for both modes.Project, CSS Module files are parsed and inspected, diagnostics are reported, and .d.ts files are emitted.Projectmaintains internal caches for the parsing, checking, and emitting stages. When notified of file changes byrunCMKInWatchMode, it discards the relevant caches.Project#276
