The default -m/-b wordlist path was derived from sys.argv[0], which under
`uv run cloud_enum` is the console-script shim in .venv/bin. The default
became .venv/bin/enum_tools/fuzz.txt, so the tool exited with "Cannot
access brute-force file" even when -m was passed. Resolve it from the
module's own __file__ instead.

fuzz.txt was also never declared as package data, so clean wheel builds
(uv tool install, pip install .) shipped without it. Declare it under
[tool.setuptools.package-data].

Add a regression test that runs parse_arguments with argv[0] pointing at
a venv shim.

- utils.py pointed at a requirements.txt that no longer exists; the
  missing-dependency message now says to run 'uv sync'
- -ns help text omitted its 1.1.1.1 default
- README: regenerate the usage block from the real --help output, correct
  the cloudenum/ -> enum_tools/ regions paths, document uv tool install
