Install tailscale and uv through pacman instead of curl

[dlebedinsky]

Right now, tailscale is installed by piping curl into sh, which is considered suboptimal from a security standpoint, and it's harder to automatically update if it's installed this way. Tailscale developers now support installation as an Arch package, so you can follow the instructions there to update the script.

This is also the case with uv, it is now officially in the Arch Extra repository and can be installed with sudo pacman -S uv

Ran into the uv half of this from the other direction: I went looking for uv in the install menu, didn't find it, and installed it by hand — not realising omarchy install dev-env python would have done it for me.

One extra argument for the pacman route that isn't in the original post: the astral installer appends its own PATH shim to the user's shell rc. On my box that left

. "$HOME/.local/share/../bin/env"

sitting in ~/.zshrc. It works, but it's surprising on a system where PATH is otherwise handled centrally via /etc/profile.d/omarchy.sh and mise shims, and it's a line that stays behind even if uv is later removed. pacman -S uv puts the binary in /usr/bin and needs no rc edit at all — plus it then tracks system updates like everything else.

Still current on dev as of today: bin/omarchy-install-dev-env:96-101. Omarchy 4.0.1-1.
