nixos: pin NVIDIA driver to 595.71.05 on ryzen-shine

Browse Source 
595.80 (nixpkgs 9b366138, 2026-06-02) introduced a GSP firmware
regression on the RTX 3070 Ti (GA104): random hard freezes with
Xid 119 / "GSP RM heartbeat timed out". 595.71.05 ran cleanly for
4.5d before the bump. Revisit when the 610.x branch stabilises.

# Pin the NVIDIA driver to 595.71.05 on this host only. nixpkgs' production
# driver moved 595.71.05 -> 595.80 (nixpkgs 9b366138, 2026-06-02), and 595.80
# introduced a GSP-firmware regression on this RTX 3070 Ti (GA104): random hard
# freezes with "GSP RM heartbeat timed out" / Xid 119 GSP RPC timeouts (see
# boots from 2026-06-08 onward). 595.71.05 ran cleanly for 4.5d before the bump,
# and the open module can't disable GSP, so we pin the last-good build directly.
# Hashes lifted from the parent of the nixpkgs bump commit. Revisit once a newer
# driver branch (e.g. the 610.x new_feature branch) is confirmed stable here.
