Binyang Li 4a0d5b29d5 Simplify torch-integration tuning example ...

- Drop the multi_host_mnnvl-specific rsag fallback in _default_ar_config;
  fall through to default_allreduce_packet when NVLS is unavailable.
- Add SYMMETRIC_MEMORY env var so the tuning sweep can include the
  zero-copy NVLS / RSAG candidates without editing the source.
- Make _algo() raise on miss (direct dict lookup) and drop the
  defensive 'if a:' guards in _ar_candidates / _ag_candidates /
  _default_ar_config; merge existence checks into the platform
  conditions (self._nvls, self.symmetric_memory).
