(1) Directly write to file in BlobWriter::Add and destruct the MatOwner to release the rams.
(2) Write a fake header to indicate this is V2, and write correct header and directory at the end of the file.
(3) Tested on loading sbs written the old way, and new way, both worked.

Activations was over-parallelized, use single pool instead.
Also improve profiler zone annotations,
pass through worker args (for tracking concurrency), now non-optional.
PiperOrigin-RevId: 788790976
Optimizations
- Better load-balancing in attention threading
(Previously, clusters were limited by #heads)
- Add MulByConstTo to avoid zero-init
- Parallel activations
Cleanup
- Prepare for RowPtr in A or B
- Pass through thread_id to ops
- Avoid warning in bench_matmul

ops-inl.h: Vectorize Rope(), template
Remove unused MulBy, and extra-arg overloads of MulByConst and Softmax
Fix for DecompressAndZeroPad: ensure second vector filled

Linux terminals truncate input after 4096 chars.
testdata is Frankenstein from project Gutenberg, which are long out of copyright.
Also fix loss of coherence after long context caused by incorrect IsGlobalLayer.
Move that to config.h and use max_seq_len as the initializer to make this clear.
Also avoid dynamic allocation for GriffinActivations.
PiperOrigin-RevId: 772333225
Fix missing pos increment for last prefill and check that in gemma_test.
Thanks to @ufownl for pointing this out.
Change argument lists to QBatch with accessors.
Increase default seq_len to 8k.

Must not pass image tokens to the EmbedMMToken used for text.
Caught by next presubmit test.
paligemma_test: move function bodies into class, regroup variables
PiperOrigin-RevId: 770040014
Parallelize over queries instead of tokens
introduce non_eos so we only iterate over not yet EOS queries; remove TokenStreamer.
move RMSNormInplaceBatched out of Transformer to call the latter from prefill
Consistent arg order.
Fix gemma_test EOS handling which (caught by msan), remove from tokenizer.h
Also add output to gemma_batch_bench, fix name
PiperOrigin-RevId: 769676106
BF16 att_sums and ffw_out
Support BF16 B views without decompression
Support arbitrary types in MulByConstAndAdd, AddFrom
Also update profiler annotations in ops-inl.h
PiperOrigin-RevId: 766995010
Detect PaliGemma models from layer names
Remove unused allocator arg from CreateInvTimescale
matmul: only warn once about dim divisibility
Print config also in tests if --verbosity 2
PiperOrigin-RevId: 766605131
This replaces per-weight instantiations of all code with only per-MatMul/norm.
Reduces binary size by 133KiB.
WeightsOwner is no longer required for type erasing, hence it is replaced with ModelWeightsPtrs.
Also remove unused EmbedToken, replaced with EmbedMMToken.
PiperOrigin-RevId: 766497657
Precompute row pointers.
Remove no longer used MHA support; QStride -> qkv_dim.
Remove RowPtr from MatMul interface, use only MatPtrT.
Require opt-in define for NUQ to speed up builds.
Also fix io.cc on Windows.
