ViperEkura cdf9145ecf docs: align CUDA kernel and RoPE docs with code 
- Fix rotary docs to describe cos/sin freqs_cis table, not complex buffer
- Replace attn_prefill with attn_paged_prefill for the CudaBackend path
- Register attn_paged_prefill in kernel overview, layout, and module list
- Add qo_indptr and InferenceWorkspace to architecture class diagram
- Add FrequencyPenaltyStrategy to sampling design patterns

ViperEkura 3439e3104e perf: launch CUDA kernels on torch's current stream 
- Thread a cudaStream_t through attn dispatchers onto torch's current stream
- Scope the device guard to the entry function so kernels run on tensor device
- DISPATCH_HEAD_DIM now forwards varargs so stream reaches each dispatch
- Parallelize CPU reference kernels with OpenMP (paged test 31s -> 7s)
- Merge decode/prefill standalone tests into attn_test.cu with correctness tables
- Drop bench error column (CPU ref too slow at large sizes)
- Update cuda_kernels.md for the merged test layout

ViperEkura 7aa5ed09d9 refactor: unify rotary embedding interface and update docs 
- Merge cos/sin into single freqs_cis tensor [batch, seq, dim/2, 2] throughout the pipeline: RotaryEmbedding buffer, forward return type, apply_rotary_emb signature, CUDA kernel interface
- CUDA kernel now takes freqs_cis directly and reads cos/sin via stride offset internally, eliminating Python-side slice/copy overhead
- Kernel interface: rotary_emb(x, freqs_cis) replaces rotary_emb(x, cos, sin)
- All call sites pass rotary_emb as Tensor (was tuple), type annotations consistent
- Update build threads from 8 to 16
- Fix all docs: get-started, inference, training, cuda_kernels, architecture, internals — reflect new rotary interface, KVCache fields, rotary backend dispatch, .so path, kernel registry count, file layout

ViperEkura 97114b95a4 docs: update for attention backend and extension API 
- Remove stale 'not yet wired' references
- Add AttentionBackend/CudaBackend sections to cuda_kernels.md, internals.md, inference.md
- Add astrai.extension to architecture.md module table and design patterns
- Update get-started.md: CUDA kernels activatable via attn_backend()

ViperEkura c8b1e40f71 docs: restructure to docs/, add guides and developer docs 
- Rename assets/ to docs/, split into guides/ and developer/
- Add get-started.md: installation + 5-step quickstart
- Add guides/evaluation.md: 7 eval scripts with CLI args
- Add guides/distributed.md: DDP/FSDP, gradient accumulation, NCCL
- Add developer/internals.md: loss formulas, RoPE, KV cache math
- Add developer/cuda_kernels.md: build system, benchmarks, file layout
- Fix storage_format doc in preprocessing.md
- Update cross-references in README.md, README-zh-CN.md, Dockerfile
