info (plus a doctor alias) now reports the binary that will actually
launch for the resolved license instead of whatever is cached on disk:
it resolves and validates the license, shows the real tier, and on a
keyless or invalid key reports the free binary. Adds a launch test
(chrome --version) with a Linux missing-shared-library probe, a
Windows-font check (Linux only), GeoIP DB presence, and optional-dep
checks. --quick skips the launch test; --json emits machine output.
Python, JS, and .NET, with tests.
