* chore(theseus): significantly cleanup MacOS-specific code
* fix(labrinth): only use jemalloc allocator for Linux targets
The upstream crate asserts that its tests only pass for Linux targets,

Labrinth deployments run under a Linux environment anyway. This change
made it easier for me to cross-compile Labrinth.
* chore(theseus): tweak traffic lights pos according to https://github.com/modrinth/code/commit/c39bb78e38cb9cfe13f01f4a9bee277881b52efb

additions of 6 and 12 units to the traffic light position calculations,
not directly modifying the `const` values introduced by
https://github.com/modrinth/code/commit/d6a72fbfc4613a45acaa38e0e73da9bcc455e87a.
