feat: add Quarto themes and templates (revealjs, HTML, PDF, Typst)

Integrate Civilytics Reveal.js slide extension, HTML/PDF/Typst document themes, and _brand.yml into the package under inst/quarto/. Three new helper functions (use_civilytics_revealjs, use_civilytics_theme, use_civilytics_brand) copy assets into a user's Quarto project. Logos are stored once in inst/img/ and distributed at install time.

+abstract: |
+  We combine ACS 5-year microdata with HUD Fair Market Rent estimates
+  to track changes in rent burden across 12 metropolitan counties.
+  Between 2019 and 2024, the share of renter households spending more
+  than 30% of income on housing rose by 6.4 percentage points; the
+  increase was concentrated in counties where median wages stagnated.

+## Background
+
+Rent has outpaced wages in every county we studied. In some, the gap is
+modest and recent; in others, it has been widening for a decade. This
+report disaggregates the trend along three lines: county, income
+quintile, and household composition.

+
+## Recommendations
+
+1. Targeted rental assistance keyed to local wage trajectories.
+2. Quarterly publication of rent-burden indicators by county.
+3. Coordinated reporting between HUD and county human-services offices.
