chore: fige Cargo.lock (mimalloc)

Declare mimalloc en #[global_allocator] sur le binaire rqbit. L'alloca-
teur systeme se comporte mal sur la charge de rqbit, faite de tres
nombreuses petites allocations concurrentes sur les buffers de pieces.

default-features = false pour ne pas embarquer les variantes secure et
les stats de debug, inutiles ici.

Ce patch tournait deja dans les paquets installes sans exister dans git,
comme la feature « delete all ». Repere par le check hygiene.
