exhaustively check `dependencies_in_sync`

super().dependencies_in_sync() ultimately calls dependencies_in_sync on self.dependencies_complex.

    def dependencies_in_sync(self):
        if not self.dependencies:
            return True

        from hatchling.dep.core import dependencies_in_sync

        with self.safe_activation():
            return dependencies_in_sync(
                self.dependencies_complex, sys_path=self.virtual_env.sys_path, environment=self.virtual_env.environment
            )

Instead of self.dependencies_complex an exhaustive list of dependencies should be read from the requirements file. pip-tools gives a nice way to access the pip API:

from typing import Iterator, List

from piptools._compat.pip_compat import InstallRequirement, PipSession, parse_requirements

reqs: Iterator[InstallRequirement] = parse_requirements(
    "requirements.txt",
    session=PipSession(),
)
piptools_dependencies_complex: List[InstallRequirement] = list(reqs)
