bug/Dependency resolution discrepancy for numba

**Describe the bug** When installing `unstructured==0.18.31`, different package managers resolve the numba dependency to different versions: `pip`: Resolves to `numba==0.63.1` (compatible with Python 3.12) `uv`: Resolves to `numba==0.53.1` (requires Python <3.10, incompatible with Python 3.12) The package declares unstructured as supporting Python 3.10, 3.11, and 3.12 (per classifiers and Requires-Python: >=3.10.0), but the unpinned `numba` dependency in the package metadata allows resolver tools to select incompatible versions. **To Reproduce** Run `uv pip install unstructured==0.18.31` in a new/clean virtual environment. ``` RuntimeError: Cannot install on Python version 3.12.12; only versions >=3.6,<3.10 are supported. hint: This usually indicates a problem with the package or the build environment. help: `llvmlite` (v0.36.0) was included because `unstructured` (v0.18.31) depends on `numba` (v0.53.1) which depends on `llvmlite` ``` **Expected behavior** Installation should complete without error **Suggested fix** Pin `numba` to `>=0.63.0` in `constraints.txt`
