chore: resolve latest bincraft release dynamically

Replace the hardcoded bincraft pin (@vX.Y.Z, repeated across every .crow
workflow and the build-one image) with local/install-bincraft.R, which lists
the remote tags via git ls-remote, picks the highest vX.Y.Z, and installs it
with pak (idempotent on the git ref). Now a new bincraft release is picked up
automatically on the next run -- no more editing the version in many places.

Filtering/sorting is done in R (not git --sort / refspec) for portable
behaviour, and GIT_TERMINAL_PROMPT=0 keeps non-interactive runs from hanging.
