* fix: improve numerical stability by conditionally using float32 in block computations
* doc: update README for improvement stability for fp16 training on Anima in version 0.10.3
Allow users to control the number of iterations for torch.svd_lowrank
on large matrices. Default is 2 (matching PR #2240 behavior). Set to 0
to disable svd_lowrank and use full SVD instead.

* docs: add skip_image_resolution option to config README
Document the skip_image_resolution dataset option added in PR #2273.
Add option description, multi-resolution dataset TOML example, and
command-line argument entry to both Japanese and English config READMEs.

* feat: Add LoHa/LoKr network support for SDXL and Anima
- networks/network_base.py: shared AdditionalNetwork base class with architecture auto-detection (SDXL/Anima) and generic module injection
- networks/loha.py: LoHa (Low-rank Hadamard Product) module with HadaWeight custom autograd, training/inference classes, and factory functions
- networks/lokr.py: LoKr (Low-rank Kronecker Product) module with factorization, training/inference classes, and factory functions
- library/lora_utils.py: extend weight merge hook to detect and merge LoHa/LoKr weights alongside standard LoRA
Linear and Conv2d 1x1 layers only; Conv2d 3x3 (Tucker decomposition) support will be added separately.

* feat: Enhance LoHa and LoKr modules with Tucker decomposition support
- Added Tucker decomposition functionality to LoHa and LoKr modules.
- Implemented new methods for weight rebuilding using Tucker decomposition.
- Updated initialization and weight handling for Conv2d 3x3+ layers.
- Modified get_diff_weight methods to accommodate Tucker and non-Tucker modes.
- Enhanced network base to include unet_conv_target_modules for architecture detection.
* fix: rank dropout handling in LoRAModule for Conv2d and Linear layers, see #2272 for details
* doc: add dtype comment for load_safetensors_with_lora_and_fp8 function
