fix torch version requirement for flashinfer compatibility

[kofi-bhr]

fix torch version compatibility issue with flashinfer wheels

the torch requirement in pyproject.toml (torch>=2.5.1) was incompatible with the flashinfer wheels which are built for torch2.4. this change updates the requirement to torch>=2.4.0,<2.5.0 to ensure users can install both packages without version conflicts.

this addresses issue #72

changes:

• updated torch dependency in pyproject.toml
• updated changelog to document the change

tested by:

• verifying versions are compatible with the flashinfer wheel path in the readme
