Subject: [PATCH] perf(ci): switch to nix-quick-install-action for faster CI

Replace cachix/install-nix-action with nixbuild/nix-quick-install-action.
This reduces Nix installation time from ~30s to ~1s on Linux.

Key benefits:
- Single-user installation (no daemon overhead)
- Deterministic installation for a given action version
- Minimal setup optimized for CI environments

Measured improvement: Setup Nix step reduced from 25s to 19s (~24% faster)
