harmonia-v3.0.0

What's Changed

Highlights

• Rust-based nix daemon replacing C++ nix-daemon:
  harmonia-daemon is a pure-Rust implementation of the Nix daemon protocol that speaks directly to the store database, eliminating the dependency on the C++ nix-daemon
  by @Mic92 in #570
• NixOS module: services.harmonia-dev.daemon.enable:
  New option to run the Rust-based daemon instead of depending on
  the C++ nix-daemon. When enabled, harmonia-cache automatically
  connects to the harmonia-daemon socket. The cache options moved
  under services.harmonia-dev.cache.* (old paths are aliased)
  by @Mic92 in #570
• Prometheus metrics and Grafana dashboard:
  Built-in metrics endpoint with a ready-to-use Grafana dashboard
  by @Mic92 in #570
• Landing page with public keys:
  New landing page showing cache configuration and public keys, with automatic URL scheme detection for HTTP-only deployments
  by @Mic92 in #647
  #653
• Drop support for daemon protocol versions < 1.37:
  Only Nix 2.24+ is now supported
  by @Mic92 in #643
