\title{Estimate free system RAM in megabytes}
\usage{
get_free_ram_mb()
}
\value{
Numeric scalar (MB of free RAM), or \code{NA_real_} if undetermined.
}
\description{
Cross-platform, base-R-only (shells out; no new package dependency).
Never errors: returns \code{NA_real_} if detection fails or the platform is
unrecognized, so callers must treat \code{NA} as "unknown" and fall back to a
fixed threshold rather than skipping the guard entirely.
