## Summary
Fixes mypy type errors across 4 model implementation files (Phase 2d of
mypy suppression removal plan):
- `src/llama_stack/models/llama/llama3/multimodal/image_transform.py`
(10 errors fixed)
- `src/llama_stack/models/llama/checkpoint.py` (2 errors fixed)
- `src/llama_stack/models/llama/hadamard_utils.py` (1 error fixed)
- `src/llama_stack/models/llama/llama3/multimodal/encoder_utils.py` (1
error fixed)
## Changes
### image_transform.py
- Fixed return type annotation for `find_supported_resolutions` from
`Tensor` to `list[tuple[int, int]]`
- Fixed parameter and return type annotations for
`resize_without_distortion` from `Tensor` to `Image.Image`
- Resolved variable shadowing by using separate names:
`possible_resolutions_list` for the list and
`possible_resolutions_tensor` for the tensor
### checkpoint.py
- Replaced deprecated `torch.BFloat16Tensor` and
`torch.cuda.BFloat16Tensor` with
`torch.set_default_dtype(torch.bfloat16)`
- Fixed variable shadowing by renaming numpy array to `ckpt_paths_array`
to distinguish from the parameter `ckpt_paths: list[Path]`
### hadamard_utils.py
- Added `isinstance` assertion to narrow type from `nn.Module` to
`nn.Linear` before accessing `in_features` attribute
### encoder_utils.py
- Fixed variable shadowing by using `masks_list` for list accumulation
and `masks` for the final Tensor result
## Test plan
- Verified all files pass mypy type checking (only optional dependency
import warnings remain)
- No functional changes - only type annotations and variable naming
improvements

Co-authored-by: Claude <noreply@anthropic.com>
Migrates package structure to src/ layout following Python packaging
best practices.
All code moved from `llama_stack/` to `src/llama_stack/`. Public API
unchanged - imports remain `import llama_stack.*`.
Updated build configs, pre-commit hooks, scripts, and GitHub workflows
accordingly. All hooks pass, package builds cleanly.
**Developer note**: Reinstall after pulling: `pip install -e .`
