* mtmd: add granite-speech support (ibm-granite/granite-4.0-1b-speech) Conformer encoder with Shaw relative position encoding, QFormer projector, log-mel spectrogram with frame stacking. Encoder uses GLU gating, folded batch norm, and SSM depthwise conv. QFormer compresses encoder output via windowed cross-attention (window=15, queries=3) into the LLM embedding space. Audio preprocessing: reflect-padded STFT, 80-bin mel filterbank, dynamic range compression, 2x frame stacking (80->160 mel). GGUF converter handles batch norm folding at export time, fused K/V split, and Conv1d weight reshaping. Tested against HF transformers reference: token-for-token match on 30s/60s audio clips with greedy decoding. * mtmd: rename gs_ prefixed tensors to generic/architecture names * mtmd: use tensor_mapping.py for all granite_speech tensors * convert: fold GraniteSpeechTextModel into GraniteModel * mtmd: replace n_layer hack with explicit has_standard_layers flag * mtmd: replace hardcoded magic numbers with GGUF hparams for granite speech * mtmd: align KEY_A_ define spacing * convert: register GraniteModel for GraniteSpeechForConditionalGeneration * convert: fix ty type-check for GraniteSpeechMmprojModel registration * mtmd: align TN_ define spacing * mtmd: use generic layer loop for granite speech tensor loading * mtmd: merge qformer_proj_layer into clip_layer * mtmd: granite_speech remove redundant ggml_build_forward_expand on inputs * mtmd: granite_speech add comment explaining why build_attn is not used * mtmd: granite_speech hard-code eps in cpp, remove from GGUF metadata * gguf: add spacing between granite_speech tensor mapping blocks * mtmd: make generic audio layer_norm_eps read optional * mtmd: granite_speech keep encoder eps in GGUF, only hard-code projector eps * mtmd: align defines and struct fields in clip-impl.h and clip-model.h * mtmd: fix alignment and ordering issues across granite speech files * convert: granite_speech use filter_tensors instead of modify_tensors for skipping
