v0.9.1

Fixes

• gpu: Fixed a crash on hosts with Intel GPUs. Reading certain hwmon sysfs
  attributes (e.g. fan1_input) can make the kernel surface a
  TypeError: can't concat NoneType to bytes from fh.read() instead of an
  OSError. read_text() only caught OSError, so the exception propagated up
  through sample() → _tick_body → tick and killed the TUI after running
  for a while.

  • read_text() now degrades to None on any read error — it is the single
    choke point for every sysfs string/int read and must never raise.
  • GpuProvider.sample() now degrades to an unavailable snapshot if any backend
    read raises unexpectedly, so one flaky read can no longer crash the tick loop.

  Both layers are covered by new regression tests.

To upgrade: pip install -U vllmstat
