Razvan Dimescu 4f6159d961 refactor(linux): switch to DynamicUser=yes, drop install-time user creation
AUR installs never call `numa install` — PKGBUILD drops the unit straight
into /usr/lib/systemd/system and the user runs `systemctl enable numa`.
With User=numa the Rust installer's useradd code never fires there,
breaking Arch out of the box.

DynamicUser=yes sidesteps packaging entirely — systemd allocates a
transient UID per start and remaps StateDirectory ownership (including
legacy root-owned trees) automatically. Works on any modern systemd.

Drops the ensure_numa_user_linux/chown helpers plus NUMA_USER; the
unit file alone now captures the privilege-drop story.
