Description
I use tsc --watch a lot but whenever I rename a file tsc --watch goes stale and doesn't recover from it hence I end up with stale JS without noticing. What you get in the console:
[1:13:49 PM] File change detected. Starting incremental compilation...
error TS6053: File '/..../npm/importLinker.ts' not found.
[1:13:50 PM] Found 1 error. Watching for file changes.
We should either fix this in TSC or at least make the task detect this and automatically restart.

Research direction
Reproduce the failure using tsc --watch and a renamed source file, then trace the watch-mode handling from that entry point. Done means the watcher recovers after the rename and no longer leaves stale JavaScript without reporting a recoverable state.
