dylanyunlon e02134a3ce [MUH] Delete 20 dead-code batch-generated tuning headers
Audit results:
  - 20/20 files had IDENTICAL if-branch and fallback (dead code)
  - 787 lines total, 5% coverage of 15116 lines in CCCL originals
  - No type specializations, no offset_size branches, no benchmark data
  - 0 of 20 algorithms appear on vllm's Qwen3.6 inference hot path

The 6 headers that remain (reduce, topk, scan, transform, batch_memcpy, for)
are the only algorithms that execute during vllm decode/prefill/cache operations.
These 6 have real type specializations and CCCL SM100 reference values.

CCCL has 26 algorithms because it's a general-purpose library.
muh targets one workload: Qwen3.6-35B-A3B on 4× BI-V100.
Covering algorithms that don't execute is worse than not covering them —
it creates the illusion of completeness.
