- Add DESCRIPTION with explicit dependencies and GitHub remotes
for statdown and depkit
- Switch renv snapshot type from "implicit" to "explicit" so
dependencies are declared, not scanned from source files
- Regenerate renv.lock: adds statdown, depkit, httr2, svglite;
bumps 9 CRAN packages; pins GitHub SHAs for custom packages
- Rename scripts/renv.lock to scripts/install-packages.R (it was
an R install script, not a lockfile)
- Bump renv 1.1.7 -> 1.1.8
