Expand description

Shared SEXP-dispatch shell for coerced numeric/logical/raw vectors.

Reads INTSXP/REALSXP/RAWSXP/LGLSXP and applies the per-element map. The only behavioural axis (NA policy) lives entirely in the four closures the caller passes, so the NA-unaware try_from_sexp_numeric_vec and the NA-aware try_from_sexp_numeric_option_vec (in na_vectors) share one dispatch. LGLSXP NA (NA_LOGICAL) and INTSXP NA (i32::MIN) round through as raw sentinels here; any NA-to-None policy is the caller’s closure to encode.
