It seems to me that the natural and obvious pronunciation of those
letters is "yashar", so the fact that the sefer is known as "yosher",
a far less obvious pronunciation, proves that it is the correct one.

Also, most titles of seforim in the form "shaarei X" describe what
the gates lead to, rather than the person who uses them.  It's more
likely that this title conforms to that model than that it doesn't.
(I dismiss the third possibility, that "yashar" refers to the author,
since that would be the opposite of humility.)
