Inconsistent prose citations for authored vs edited works

[LaurenceOMFoisy]

Description

Description

When using prose citations (form: "prose"), Typst handles authored and edited works differently. For authored works, it correctly shows "Author (Year)" but for edited works, it only shows "(Year)".

Minimal Working Example

#let pc = (citation) => {
  set cite(form: "prose")
  citation
}

#pc[@downs57] // correctly shows "Downs (1957)"
#pc[@brady_collier10] // incorrectly shows only "(2010)"

#bibliography("references.bib", style: "apa")

@book{downs57,
  title = {An Economic Theory of Democracy},
  author = {Downs, Anthony},
  date = {1957},
  edition = {1},
  publisher = {Harper \& Row},
  location = {New York},
  langid = {english}
}

@book{brady_collier10,
  title = {Rethinking Social Inquiry. Diverse Tools, Shared Standards},
  editor = {Brady, Henry E. and Collier, David},
  date = {2010},
  edition = {2},
  publisher = {Rowman \& Littlefield Publishers},
  location = {Maryland}
}

Expected Behavior
Both citations should show the names followed by the year in parentheses:

#pc[@downs57] → "Downs (1957)"
#pc[@brady_collier10] → "Brady and Collier (2010)"

Actual Behavior

#pc[@downs57] → "Downs (1957)" (correct)
#pc[@brady_collier10] → "(2010)" (incorrect - missing editors' names)

Additional Information

The issue persists regardless of CSL style used
The issue appears to be related to how Typst handles editor vs author fields in prose citations
Using the @ symbol for regular citation works correctly with editors instead of authors.

We may need to modify the do_author closure, starting from these lines:

hayagriva/src/csl/mod.rs

Lines 1249 to 1250 in 21f0185

	let do_author = |ctx: &mut Context<'b, T>| {
	let author_var = Variable::Name(NameVariable::Author);

to use NameVariable::Editor if NameVariable::Author is not available.
