Zijie Tian 6e34efd58a 📝 docs: add storage overhead analysis and batch tests for KV chunking ...

- Update xattn_kv_chunking_kernels.md with:
  - Detailed storage overhead analysis (O(S) vs O(S²))
  - Peak memory optimization (8x reduction)
  - Support for independent Q/KV chunk sizes
  - Batch verification results (3K-64K seqlen)
  - ASCII pipeline diagram

- Add test_xattn_kv_chunking_batch.py for batch validation
- Fix causal mask post-processing in alignment test
- Update CLAUDE.md documentation index
