perf(local): skip per-minor passes for non-r-minor-sensitive packages

Browse source 
A package's ABI sensitivity is the same across R minors, so for a non-sensitive
package the per-minor loop only ran `ensure_bincraft` (a ~14s bincraft/cranlike
install per minor) before build-one.R classified and skipped it. The primary
pass now writes a .r_minor_sensitive sentinel when it builds a sensitive
package, and the wrapper gates the whole per-minor loop (installs included) on
that file — non-sensitive rebuilds no longer touch other minors' libraries.
