The installer workflow had not been touched since 2024 and missed
both the Ubuntu 26.04 runner bump and the move to Determinate Nix as
the common Nix. Bring it in line with `ci.yaml`.
The Go setup step stays: it supports the Gitea release action rather
than the Nix build.

Use Determinate Nix as `nix.package` for systems, homes and the
devshell, for its parallel evaluation and lazy trees. We only take the
package, not `determinate-nixd`: the daemon and `nix.conf` model are
unchanged and the Determinate NixOS module is not imported.
- Add the `determinate-nix` (`nix-src`) input, following our
`nixpkgs-unstable`. FlakeHub's cache needs auth, so we build it
ourselves and let it flow through Harmonia like everything else.
- `determinateOverlay` exposes it as `pkgs'.mine.determinate-nix`;
`lib.my.c.nix.determinateSettings` (`lazy-trees`, `eval-cores = 0`)
is merged into `nix.settings` and the devshell `nix.conf`.
- Switch CI to `DeterminateSystems/determinate-nix-action` so the
runner itself evaluates with Determinate.
- Advertise the Harmonia cache via the flake's `nixConfig`, trusted
without a prompt via `accept-flake-config` in the devshell, `.envrc`
and CI only (boxes already trust it through `nix.settings`).
- Re-attach `pkgs`/`lib` to container and installer
`nixosConfigurations` so Determinate's flake schemas can evaluate
them (`nix flake check` otherwise fails with `attribute 'pkgs'
missing`).
