* feat: Add a verbose log for each tensor loaded

This is really helpful for diagnosing mismatches between the expected and
received tensors

* feat: First (broken) pass at nemotronh model architecture

It generates tokens, just not valid ones!

* fix: Explicitly enable add_bos_token during conversion

The `tokenizer.json`/`tokenizer_config.json` in the model are a bit
contradictory. In the config, add_bos_token is set to False, but the
tokenizer model itself has a post_processor that adds the BOS token via
type: TemplateProcessing

* Nemotron-H: MLP gate cleanup (pass NULL for unused gate)

This model does not use a gate in MLP blocks; pass NULLs for gate tensors to make intent clear and avoid unused-pointer noise.

* SSM: respect ssm_dt_rank for dt_dim when provided

Use GGUF-provided time_step_rank (ssm_dt_rank) to set dt_dim when > 0; fallback to max(64, n_embd/16).

* fix: plamo2 - revert dt_dim to default (remove ssm_dt_rank usage)

* Rename nemotronh to nemotron_h for consistency

- Update architecture name from NEMOTRONH to NEMOTRON_H in constants.py
- Change architecture string from 'nemotronh' to 'nemotron_h' in all files
- Update enum LLM_ARCH_NEMOTRONH to LLM_ARCH_NEMOTRON_H
- Update class name llm_build_nemotronh to llm_build_nemotron_h
- Consistent naming with underscore convention (nemotron_h vs nemotronh)

* feat: Support conversion for older NemotronH models
