🧹 Nitpick | 🔵 Trivial

Pin CRAN snapshot for reproducible builds.
Using latest can shift binaries over time. Prefer a dated snapshot URL to keep images deterministic.

♻️ Example update 
-ENV CRAN_REPO="https://packagemanager.posit.co/cran/__linux__/bullseye/latest"
+ENV CRAN_REPO="https://packagemanager.posit.co/cran/__linux__/bullseye/2026-01-23"

In `@ir/ir-with-libs/Dockerfile.ir` around lines 50 - 52, The CRAN repo is set to
a moving "latest" snapshot via the ENV CRAN_REPO variable; replace that value
with a dated Posit Package Manager snapshot URL to pin binaries for reproducible
builds (update the ENV CRAN_REPO entry in Dockerfile.ir to a specific snapshot
date, e.g. use the Posit snapshot path with a YYYY-MM-DD segment instead of
"latest"). Ensure the ENV CRAN_REPO assignment is updated wherever it appears so
builds use the fixed dated snapshot.
