nerd-deck app 0.9.1

What's changed

Everything since host-v0.9.0.

Fixes

• stats: stop leaking GPU and mount watchers, and read less often (dd6683d)
  Changing a Stats setting built a new collector, which started another GPU
  watcher and mount watcher while the old ones kept running; the collector is
  now reconfigured in place. Clock speeds, disk space and the CPU's
  temperature are read at most once a second, and network counters come from
  /proc/net/dev, one file, instead of six files per interface.

Performance

• drop sysinfo's thread pool (2a2f0b7)
  Its rayon threads, one per core, were woken on every sample to refresh in
  parallel, which cost far more than the refresh itself: about 3.5% of a core
  at a 100 ms interval.

Chores

• release: app 0.9.1 (5856da5)
