`hatch build` stopped working with hooks in 1.16.0

We use the hatch-protobuf plugin to generate protobuf stubs with the following configuration:

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

[tool.hatch.build.hooks.protobuf]
dependencies = [
    "hatch-protobuf~=0.4.0",
    "grpcio-tools",
    "mypy-protobuf",
    "protobuf",
]

However, starting from version 1.16.0, the hatch build command generates an error:

Traceback (most recent call last):

hatchling.plugin.exceptions.UnknownPluginError: Unknown build hook: protobuf

Other hatch commands, such as run, fmt, and test, as well as direct installation via pip, work correctly. It's likely that hatch doesn't install hook-level dependencies into a build environment.

Reproduce the failure with the shown build-system configuration and hatch build. Start in hatchling/builders/plugin/interface.py, especially get_build_hooks, and follow the build path from hatchling/cli/build/__init__.py. Done means the protobuf hook is discovered in the build environment and the sample project builds successfully.
