forth: make "(entry)" call WORD itself
...
Otherwise, when a defining word would be called outside a definition
itself, it would get the name of the last parsed word, that is,
itself!
For example, dummy.fs, instead of creating a "_______" entry, created
a "(entry)" entry...

Forth-ification of Collapse OS goes forward. What will happen is that assembly
code in apps/ will become Forth code. The concept of an assembler code library
will become obsolete.
However, Forth's core use some of that code. To facilitate the transition, I'm
inlining that code directly in Forth's code.
