Memory diagnostics

pub fn store_memory() -> text

Returns a multi-line snapshot of all LIVE stores' internal memory utilisation: total capacity vs actual claimed data vs free space, record + free-block counts, mergeable adjacent-free pairs (free neighbours that should have coalesced), and the largest stores by capacity with their creation site (bc:<pos> — a bytecode position on the interpreter; 0 on --native) and type name. Use to watch memory growth in a running program.
