File watching errors no longer blow up as unhandled crashes when nothing is listening for them.

What

The watcher checks the error listener count before emitting, so a watch error or an error during a pending write can no longer surface as an unhandled 'error' event.

Details
  • Check sits alongside the existing ENOENT/ENOTDIR filtering and the ignorePermissionErrors option.
  • In the pending-write path, when no error listeners are registered the pending write is discarded rather than emitting an ERROR event.
Evidence

_pendingWrites, ignorePermissionErrors

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
