examples : add debug utility/example (#18464)
* examples : add debug utility/example

This commit introduces a new example named llama-debug which is a
utility that is intended to be used to assist with developing/debugging
a converted model.

The motivation for this utilitiy is to assist in model conversion work
to verify that the model produces the expected outputs. It is intended
to replace logits.cpp in examples/model-conversion.

Example usage:
```console
./build/bin/llama-debug \
    -m models/Qwen2.5-0.5B-Instruct.gguf \
    --prompt "Hello, my name is" \
    --save-logits
...
Model add_bos: false
Input prompt: "Hello, my name is"
Token ids (5):
Hello(9707) ,(11)  my(847)  name(829)  is(374)
Data saved to data/llamacpp-Qwen2.5-0.5B-Instruct.bin
Data saved to data/llamacpp-Qwen2.5-0.5B-Instruct.txt
Prompt saved to data/llamacpp-Qwen2.5-0.5B-Instruct-prompt.txt
Tokens saved to data/llamacpp-Qwen2.5-0.5B-Instruct-tokens.bin
```

For more details about the options available for this example, please
refer to examples/debug/README.md.

* throw runtime error instead of logging error

* remove params.warmup and enable the warmup/nowarmup option

* model-conversion : remove logits.cpp

This commit removes logits.cpp in favor of using llama-debug for
generating logits and embeddings.

* examples : remove model-conversion directory

This was missed in the previous commit.

* model-conversion : add support for saving prompt and token ids

This commit add support for storing the prompt and the token ids for the
prompt when running the original models.

The motivation for this is that this will allow us to compare the prompt
and the tokens generated for the prompt when verifing the converted
model. Currently it is possible that even if the same prompt is used
that the tokens generated are different if there is a difference in the
tokenization between the original and converted model which would
currently go unnoticed (the verification will most likely fail but it
might not be obvious why).

* squash! model-conversion : add support for saving prompt and token ids

fix pyright errors.

* model-conversion : add compare_tokens utility

This commit adds a script to compare token outputs between original and
converted models.

Example usage:
```console
(venv) $ ./scripts/utils/compare_tokens.py pytorch-gemma-3-270m-it llamacpp-gemma-3-270m-it-bf16

Comparing tokens between:
  Original : pytorch-gemma-3-270m-it (6 tokens)
  Converted: llamacpp-gemma-3-270m-it-bf16 (6 tokens)

 All 6 tokens match!
```
And there is a verbose flag that will also print out the prompts:
```console
(venv) $ ./scripts/utils/compare_tokens.py pytorch-gemma-3-270m-it llamacpp-gemma-3-270m-it-bf16 -v

Original model prompt (pytorch-gemma-3-270m-it):
  prompt: Hello, my name is
n_tokens: 6
token ids: 2, 9259, 236764, 1041, 1463, 563

Converted model prompt (llamacpp-gemma-3-270m-it-bf16):
  prompt: Hello, my name is
n_tokens: 6
token ids: 2, 9259, 236764, 1041, 1463, 563

Comparing tokens between:
  Original : pytorch-gemma-3-270m-it (6 tokens)
  Converted: llamacpp-gemma-3-270m-it-bf16 (6 tokens)

 All 6 tokens match!
```

* model-conversion : add token comparison to verifiction scripts

This commit add the calling of the compare_tokens function in
compare-logits.py and semantic_check.py to ensure that the token ids
that the tokenizers procoduce are the same before proceeding with
verifying the logits/embeddings.

Placing them in the existing scripts instead calling them separately
ensures that the token comparison is always done prior to the
logit/embedding verifications.

Follow up commit/pr could refactor the causal logits verification into
a single script instead of the two that exist now. This would reduce the
code and make it consistent with the embeddings verficiation which only
has a single script.

* debug : use llama_model_n_embd_out

This commit updates the debug example to use the new function
llama_model_n_embd_out instead of llama_model_n_embd.

The motivation for this change is to support late interation retriever
models, like LFM2-ColBert-350M, where the output embeddings are down
projected to a lower dimension.

* debug : add print_usage function

This commit adds a print_usage function that is passed to the
common_params_parse.

The motivation for this is that this enables a specific usage message
which will be printed after all the options, for example:
```console
example usage:

  Print tensors:

  ./build/bin/llama-debug -m model.gguf -p "Hello my name is" --verbose

  The tensors to be printed can be filtered with --tensor-filter option.

  Save logits/embeddings:

  ./build/bin/llama-debug -m model.gguf -p "Hello my name is" --save-logits

  Add --embedding to save embeddings
```

model-conversion : remove hardcoded /bin/bash shebangs [no ci] (#15765)
* model-conversion : remove hardcoded /bin/bash shebangs [no ci]

This commit updates the bash scripts to use env instead of using
hardcoded /bin/bash in the shebang line.

The motivation for this is that some systems may have bash installed
in a different location, and using /usr/bin/env bash ensures that
the script will use the first bash interpreter found in the user's
PATH, making the scripts more portable across different environments.

* model-conversion : rename script to .py [no ci]

This commit renames run-casual-gen-embeddings-org.sh to
run-casual-gen-embeddings-org.py to reflect its Python nature.

examples : add model conversion tool/example (#15455)
* examples : add model conversion tool/example

This commit adds an "example/tool" that is intended to help in the
process of converting models to GGUF. Currently it supports normal
causal models and embedding models. The readme contains instructions and
command to guide through the process.

The motivation for this to have a structured and repeatable process for
model conversions and hopefully with time improve upon it to make the
process easier and more reliable. We have started to use this for new
model conversions internally and will continue doing so and improve it
as we go along. Perhaps with time this should be placed in a different
directory than the examples directory, but for now it seems like a good
place to keep it while we are still developing it.

* squash! examples : add model conversion tool/example

Remove dependency on scikit-learn in model conversion example.

* squash! examples : add model conversion tool/example

Update transformer dep to use non-dev version. And also import
`AutoModelForCausalLM` instead of `AutoModel` to ensure compatibility
with the latest version.

* squash! examples : add model conversion tool/example

Remove the logits requirements file from the all requirements file.
