AUR package for turborg (Arch Linux)

[stefanthearchitect]

Context

Arch users expect an AUR package. A -bin package that pulls the released archive from dl.turborg.com is low-maintenance and fits the existing release pipeline.

The task

Create and maintain a turborg-bin AUR PKGBUILD that installs the released turborg binary (and the borg symlink when free), with checksum verification against the published checksums.txt.

Acceptance

• PKGBUILD builds and installs cleanly on a current Arch box.
• Version + checksums track releases (note how you'd keep it updated).
• Referenced from the README install section.
