Fix all remaining test failures: single-cube allreduce + matplotlib dep

Browse Source

- intercube_allreduce: add single-cube fast path that skips intra-SIP
  mesh reduce and goes directly to inter-SIP exchange. Fixes IPCQ
  deadlock when TP launches kernel on one cube per SIP.
- distributed.py: derive effective cube dims from tensor shard placement
  instead of hardcoding topology mesh size.
- pyproject.toml: add matplotlib>=3.7 to dependencies.
- pe_dma.py (prior commit): add MMU translation in pipeline DMA path.

577 passed, 0 failed (was 529 passed, 10 failed).
