Quarto Chunks

• [ ] Update labels with fig-cap, fig-scap, tbl-cap, and tbl-subcap
• [ ] Simplify caption vectors with knitr format handling
• [ ] Replace bookdown cross references with quarto syntax
• [x] Use knitr v1.35+ alternative syntax (2e0134a029a967ace074c5c57d5a5bdc4ffb6444)

Syntax

Cross References

Replace inline R Markdown bookdown cross references with `quarto:

• From \@ref((fig|tbl):label) to @(fig|tbl)-label
  • Follow quarto syntax as spinal case (lowercase hyphenated) with label prefix
  • Note difference in default text vs. bookdown integer return behavior

Figures

```{r fig-<label>}
#| fig-cap: >
#|   Full caption...
#| fig-scap: >
#|   Short caption for LoF

### Tables

#| tbl-cap: >
#|   Full caption...

## Issues

* [ ] Missing support for table short captions e.g., `tbl-scap`
    + Conflict with dot fill operation for LaTeX `LoT` entries

For table captions, fig.scap does not work. Need to address conflict between period at end of table caption and LaTeX \dotfill spacing.

knitr::kable() has an argument caption.short to address this:
