bincraft dropped pak in favour of uvr, so the pipelines, helper scripts
and images in this repo move with it.
- add local/uvr-install.sh as the single replacement for pak::pak(); it
bootstraps a pinned uvr, mints a throwaway project under TMPDIR and
runs `uvr add --no-install` + `uvr sync --library`, because `uvr add`
refuses to run outside a project and only `sync` honours --library
- install bincraft via its Forgejo spec (forgejo::codefloe.com/rpkgs/
bincraft@<tag>) instead of a git:: URL, keeping the git ls-remote tag
resolution
- pass UVR_R_BIN/UVR_TARGET_LIB from install-bincraft.R so the
per-R-minor passes target their own R and library
- replace R_PKG_CACHE_DIR with UVR_CACHE_DIR/UVR_PACKAGES_DIR on the
persistent volume, preserving the amd64-off/arm64-on split
- drop trim_pkgcache_metadata() and its test; uvr's cache does not grow
the way pkgcache's _metadata dir did
- let uvr install system requirements from its vendored
r-system-requirements rules, replacing pak::sysreqs_db_update()
- migrate the shiny app image, the alpine reprex and the CRAN loading
test; ship uvr-install.sh in the build-one image
- track the uvr pin with renovate
