Description

mimalloc still complains after https://github.com/uutils/coreutils/issues/11236 was merged.
Since we cannot share FluentBundle, we should share pre-translate!d messages.

Research direction

Start by reading issue #11236 and tracing setup_localization and translate! usage in the Rust code. Identify how messages can be prepared before translation and shared across threads without sharing FluentBundle. Done means avoiding setup_localization on every thread while addressing the reported mimalloc performance complaint.
