False negative: `MassNouns` doesn't flag "a software" that has modifiers/qualifiers

> bibisco is a novel writing software that helps you plan, organize and write your story without getting lost.

"a software" is very common among nonnative users of English and has been adopted by some in the younger generation of native speakers. In this case I think the writer is a native Italian speaker.

Harper flags it in isolation as "a software" but not in "a novel writing software".

This is an interesting test case too because both "novel" and "writing" can be analysed as either adjectives or nouns though in this context "novel" is a noun and "writing" is a gerund, which is a verb used as a noun.

Correctly, the phrase should be hyphenated as "novel-writing software", but that's a separate job for a different linter and the linter that flags "a software" should be permissive about what it accepts.

Locate the MassNouns implementation and its existing tests, then start by tracing how noun phrases with modifiers are analyzed. Add a regression case for “a novel writing software” and verify that the phrase is flagged while the linter remains permissive about the separate hyphenation concern.
