Module convert 

RValue ↔ SEXP conversion.

Converts between miniR’s RValue types and the C-compatible SEXP layout used by native package code. Handles the type differences:

• miniR Integer is i64, R INTEGER is i32 → truncate with overflow check
• miniR Logical is Option<bool>, R LOGICAL is i32 (TRUE=1, FALSE=0, NA=NA_INTEGER)
• miniR uses NullableBuffer bitmaps, R uses sentinel values (NA_REAL, NA_INTEGER)
