Harden console path input against crashes

Menu.start() runs command.execute() with no surrounding try/catch, so
an unchecked InvalidPathException from Path.of() on bad user input
crashed the whole console loop. Centralize path parsing in
InputProcessor.readPath(), which now validates and reprompts instead
of throwing, and strips a surrounding pair of quotes so pasted/quoted
paths still work.
