Pin `openwrt-feeds` to repository state that includes vendored APK
indexes, keeping image builds independent of mutable upstream indexes.
Document the corresponding refresh workflow.
fergal is an 8-port SFP+ switch on a Realtek RTL9303, running OpenWrt
rather than RouterOS or UniFi. It is not part of the fabric yet, but
its firmware is now built here via astro's nix-openwrt-imagebuilder.
Packages are baked into the image: OpenWrt's package server keeps only
the current build of each feed, so installing at runtime stops working
as soon as the feed moves past the running firmware.
Those feed indexes rotate constantly, and upstream pins only the
indexes -- a mismatch drops evaluation into import-from-derivation,
putting this flake's eval on the network. The openwrt-feeds input pins
expanded per-package hashes instead, in a repository of its own
because they run to hundreds of thousands of generated lines.
Flashing gets a procedure doc and a thin skill pointing at it, the
same split as the box installation and nixpkgs upgrade procedures.

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`).

`pi-coding-agent-bun` breaks `nix flake check` in CI: its bun2nix
`fetchBunDeps` calls `builtins.filterSource` on subpaths of the pi.nix
flake source, which requires that source derivation to be realised in the
local store. A fresh CI runner doesn't have it, so eval aborts with
`path '...-source.drv' is not valid`. It only works locally because the
source is already realised there.
Not using pi right now, so comment out the input, overlays, home module
import and the package (leaving a root-cause note in `flake.nix`) rather
than working around the upstream issue.
