v0.3.1 -- rename to privacyfox --apply/--revert
Renames the command from privacyfox-apply to privacyfox, and switches from "no args = apply" to explicit flags -- caught before v0.3.0's --revert addition was ever run by anyone.
privacyfox --apply # was: privacyfox-apply
privacyfox --revert # was: privacyfox-apply --revert
Bare privacyfox (or -h/--help) now prints a real two-mode usage summary and exits 0; an unrecognized flag prints the same summary and exits 1.
v0.3.0 was published and superseded within the same session, before any real-world install -- no migration path needed for the old name.
Rebuilt, lintian-clean, man page re-rendered and checked for formatting issues before trusting it.
