chore(release): bump teleuploader 1.1.0 -> 1.1.1

Force a fresh Nix store path so the Buffer-from-gzip fix actually reaches
the VPS. The 1.1.0 store path hash was reused by Nix (identical derivation
inputs from Nix's perspective), so a version bump guarantees the fixed
dist bundle is copied and the profile is switched.
