feat(jupiter): add newsreader profile (RSSHub + Miniflux)

X killed guest API access and now prices reads at $0.005 each with no free
tier, so the only workable personal news reader is a scraping bridge fed by a
burner account's session cookie.

RSSHub turns X accounts, lists and keyword searches into RSS on loopback;
Miniflux is the reader, exposed on the LAN and registered with homepage.
Both secrets live outside the Nix store as root-owned EnvironmentFiles.

Note: the packaged RSSHub reads TWITTER_AUTH_TOKEN — the username/password
login that upstream docs still describe is commented out in that build.

-### Secrets (sops-nix)
-
-Secrets are encrypted with sops, decrypted per-host from that host's SSH host
-key. `.sops.yaml` defines who can decrypt what; `secrets/<host>.yaml` holds
-the encrypted values; `machines/<host>/secrets.nix` declares which secrets
-that host exposes and consumes them via `config.sops.secrets.<name>.path`.
-Always `git add` a secrets file before `nix build` — untracked files are
-invisible to flake evaluation. Full workflow (adding a secret, adding a host,
-rotating keys): see [`docs/secrets.md`](docs/secrets.md).
-
 ### Profile / Module Pattern
 
 Every module under `modules/` follows the same structure:

-# Secrets (sops-nix)
-
-Secrets are encrypted with [sops](https://github.com/getsops/sops) and decrypted
-at activation by [sops-nix](https://github.com/Mic92/sops-nix). Each host decrypts
-with its own SSH host key (converted to an age key in-memory — no separate host
-private key is ever stored on disk).
-
-Tooling (`sops`, `age`, `ssh-to-age`) is available via `nix develop` in this repo,
-and installed system-wide on every machine via `machines/core/sops.nix`.
-
-## Adding a secret to an existing host
-
-```
-nix develop -c sops secrets/<host>.yaml
-```
-
-This opens `$EDITOR` on the decrypted content. Add your key, save, quit — sops
-re-encrypts on write. Then declare it in `machines/<host>/secrets.nix`:
-
-```nix
-sops.secrets.my-secret = {
-  owner = "someuser";   # defaults to root
-  group = "someuser";
-  mode = "0400";
-  restartUnits = [ "foo.service" ];  # if a running service needs to pick it up
-};
-```
-
-Consume it in the owning module as `config.sops.secrets.my-secret.path`
-(resolves to `/run/secrets/my-secret`) — never inline the decrypted value into
-a Nix string, since that copies it into the world-readable `/nix/store`.
-
-Then:
-
-```
-nix build '.#nixosConfigurations.<host>.config.system.build.toplevel'
-sudo nixos-rebuild test --flake '.#<host>'
-# verify, then:
-sudo nixos-rebuild switch --flake '.#<host>'
-```
-
-**The secrets file must be `git add`ed before `nix build`** — untracked files
-are invisible to flake evaluation, and `sops.validateSopsFiles` needs it in the
-Nix store.
-
-## Adding a new host
-
-1. On the new host: `ssh-to-age < /etc/ssh/ssh_host_ed25519_key.pub` to get its
-   age public key.
-2. In `.sops.yaml`: add a `&host_<name>` anchor with that key, and a
-   `creation_rules` entry for `secrets/<name>.yaml` including both the new
-   host key and `*admin_finn`.
-3. Create `machines/<name>/secrets.nix`, add it to that machine's
-   `configuration.nix` imports.
-4. If the host needs to read an existing shared file, run
-   `sops updatekeys secrets/<file>.yaml` after step 2 so it's re-encrypted to
-   include the new recipient.
-
-## Rotating keys
-
-```
-# after editing .sops.yaml (new/removed recipient):
-nix develop -c sops updatekeys secrets/<file>.yaml
-```
-
-for every file the change affects. `updatekeys` requires you to already be
-able to decrypt the file — this is why `*admin_finn` is a recipient on every
-rule, as the standing fallback.
-
-Reinstalling a host regenerates its SSH host key, which changes its age
-identity. Any file previously encrypted to that host must be `updatekeys`'d
-with the new key, or the host's next activation fails to decrypt.
-
-## Where private keys live
-
-- **Operator** (you): `~/.config/sops/age/keys.txt` — sops' default lookup
-  path, so `SOPS_AGE_KEY_FILE` never needs to be set. Never committed. Back
-  this up out-of-band (password manager, offline copy) — if it's lost, only
-  the surviving host keys can still decrypt their own files, and any file that
-  was only ever readable by an operator-only rule becomes permanently
-  unreadable.
-- **Hosts**: `/etc/ssh/ssh_host_ed25519_key` — already managed by NixOS,
-  converted to age in-memory at activation time. Nothing extra to back up.
-
-## Layout
-
-```
-.sops.yaml              # age recipients + creation rules (which keys can decrypt which files)
-secrets/<host>.yaml      # per-host encrypted secrets (default sopsFile for that host)
-machines/core/sops.nix   # applied to every machine: decryption config, sops/age/ssh-to-age on PATH
-machines/<host>/secrets.nix   # per-host: which secrets exist, owner/group/mode
-```
