fix(m1): inotify — use read_to_end for UTF-8 resilience, await spawn_blocking

- read_to_end + from_utf8_lossy replaces read_to_string so Wine/game logs
  with Latin-1 bytes are handled via U+FFFD replacement instead of silently
  dropping all events from that file
- bytes_read from I/O call used for new_pos (not content.len()) for correct
  byte position accounting
- spawn_blocking handle is now awaited so panics inside the blocking task
  surface to the caller instead of being silently swallowed
