test(fleet): keep CLI parsing regression at the CLI boundary

Move the real worker argv regression into the existing CLI test module,
preserving both policy values and parser assertions without a new Fleet
dependency on the top-level CLI. No module baseline or production changes.

Validation: focused Rust 1 passed, 0 failed, 0 ignored; module boundary
Python 23 passed; module graph baseline passed. npm test 670 passed and
check:web passed at parent 1b1744b; this follow-up changes tests only.
