feat(node): skip a file the disk stops answering for, then pause its root

A Windows tester's scan stuck for good on one directory of a large disk:
one read that never returned held the indexer's only thread, and with it
every root behind that one.

- A disk call is timed by its silence, not its length: each directory
  entry listed and each megabyte read counts as an answer. After 60 s of
  silence the call is abandoned on its daemon thread, the file is noted
  unread and the scan goes on.
- Three silent files in a row pause the root (not persisted). Resume
  skips the files already known to give no answer; a restart, a replug
  or a change to the file retries them.
- The walk is per directory with os.scandir: a subdirectory that cannot
  be listed costs itself, and a listing that stops answering pauses the
  root at once. A scan no longer stats anything from the event loop.
- The log names the file after 10 s of silence, the indexing band shows
  it, and Group settings shows the paused root, where it stuck and the
  unread files with their reason, on the node's machine only.
- generate_http_api.py writes LF on Windows too.

Verified with real kernel-blocked opens (an unacknowledged oplock) in the
installed frozen app.
