3164d8cec3 nix/matrix+gateway: server_name defaults to hive domain + .well-known routes (#660)
mara on #660: "Matrix domain should default to hive domain if not
set otherwise / redirect matrix clients with .well-known"

Two coupled changes:

1. `services.hyperhive.matrix.serverName` default flipped from
   `matrix.${services.hyperhive.domain}` (subdomain) to just
   `${services.hyperhive.domain}` (bare hive domain).

   This is a "for new deploys only" change — `server_name` is
   embedded irrevocably in every user/room ID, so existing
   homeservers must set `serverName` explicitly to preserve the
   subdomain shape if that's where their identifiers were minted.
   Description updated to point at the .well-known piece below.

2. `hive-gateway` nginx now serves matrix-spec `.well-known`
   auto-discovery JSON at the canonical location when matrix is
   enabled + hive domain set:

       GET /.well-known/matrix/client
           {"m.homeserver":{"base_url":"http://<domain>:<httpPort>"}}
           + Access-Control-Allow-Origin: *  (per matrix spec)

       GET /.well-known/matrix/server
           {"m.server":"<domain>:<httpPort>"}

   tuwunel serves both client + federation on the same `httpPort`
   (see hive-matrix.nix), so both records point at the same
   endpoint. No-op when matrix isn't enabled or hive domain isn't
   set — nothing to advertise.

Combined effect: with `services.hyperhive.domain = "darkest.space"` +
matrix enabled, a matrix client pointed at `darkest.space` resolves
through `.well-known` to the actual `:8008` endpoint, no subdomain
needed. MXIDs become `@atlas:darkest.space` (was: `@atlas:matrix.darkest.space`).

Verified via `nix eval`:
- server_name = "darkest.space" (was "matrix.darkest.space")
- gateway locations include `= /.well-known/matrix/client` + `= /.well-known/matrix/server`
- well-known/matrix/client returns the spec-shaped JSON

Caveat: `m.homeserver.base_url` advertises HTTP (no TLS yet —
follow-up). matrix clients increasingly require HTTPS for new
account creation, so the v0 setup works for local-network testing
but won't satisfy public clients until the gateway TLS story lands.

Closes #660.

85790b0cca nix: add breaking-change note to each openFirewall description (argus #653)
argus picked option (a) on #653: put the upgrade note in each option's
`description` so it shows up in `nix flake show` + the rendered
options docs, right next to the option itself. cheapest option, no
eval-time noise (a `warnings` block would fire on every new
deployment that wants false — the normal case now).

Appended a `**Breaking change as of #651**` paragraph to each of the
three `openFirewall` descriptions, naming the exact option string the
operator needs to set to restore the old behaviour.

Gateway's note specifically calls out that external reach is the
common case (operator's primary entry point), so the upgrade hint
is most likely needed there.

7feef4cc5d nix: openFirewall defaults false across forge/gateway/matrix (#651)
mara on #651: "Dont default openFirewall to true."

Flip the `openFirewall` default from `true` to `false` for all three
modules that expose host-side ports:

- `services.hyperhive.forge.openFirewall` (httpPort 3000 + sshPort 2222)
- `services.hyperhive.gateway.openFirewall` (port 80)
- `services.hyperhive.matrix.openFirewall` (httpPort 8008)

Rationale: secure-by-default. With shared host netns, the host +
every agent container reach these services via `localhost` regardless
of the firewall — the open only matters for access from outside the
host. Operators who want external reach now flip the bool explicitly:

    services.hyperhive.gateway.openFirewall = true;

Each description updated to explain the new default + when to flip
it (operator's browser, external git clients, federation announcement,
etc.). Behind a host-level reverse proxy that handles TLS, leave off.

Verified via `nix eval` on a clean stub config:
- forge openFirewall = false
- gateway openFirewall = false
- matrix openFirewall = false
- networking.firewall.allowedTCPPorts = [] (was: [80 2222 3000 8008])

Note: c0re's direct ports (7000/8000/8100-8999) are gated separately
via #621 on `gateway.enable` — that gate stays; this PR only touches
the per-module `openFirewall` knobs.

Closes #651.

b37c353f0e nix: hive-gateway v0 — nginx in front of c0re (#609)
Per mara's directive on #609: stand up a single nginx in its own
nixos-container, serve the matrix GUI static dist there, proxy
everything else to hive-c0re. v0 is HTTP-only; TLS / public-domain
shape lands in follow-ups.

New `nix/modules/hive-gateway.nix` declaring `containers.hive-gateway`
modelled on `hive-forge`:

- nixos-container running nginx, shares host netns
- `location /matrix/` → static-serves `hyperhive.matrix.gui.package`
  (fluffychat-web by default) when `matrix.gui.enable` is true
- `location /` → proxy_pass to `127.0.0.1:${dashboardPort}` with
  websocket + SSE upgrade headers + 1d read timeout

Options (`hyperhive.gateway.*`):
- `enable` (default `true`) — gateway on by default, opt out to bypass
- `port` (default `80`) — nginx listen port on the host
- `upstreamHost` / `upstreamPort` — c0re target, defaults to
  `127.0.0.1:${services.hive-c0re.dashboardPort}`
- `openFirewall` (default `true`) — open the listen port
- `localHostsEntry` (default `false`) — when true, adds an
  `/etc/hosts` entry mapping `hyperhive.domain` → `127.0.0.1` for
  local-dev / test loops without real DNS (per mara's spec)

`hive-c0re.nix` updates: when gateway is enabled, skip wiring
`HIVE_MATRIX_GUI_DIR` (gateway owns `/matrix/` now). When gateway is
off, c0re's pre-existing matrix mount stays as the fallback.

README: short "Optional" block introducing the gateway + the
`localHostsEntry` knob.

```sh
nix flake check --no-build

nix build .#docs-host
```

End-to-end eval matrix:

| gateway.enable | matrix.gui.enable | c0re HIVE_MATRIX_GUI_DIR | gateway container |
| --- | --- | --- | --- |
| true (default)  | true  | unset (gateway serves) | present |
| true            | false | unset                  | present, no /matrix |
| false           | true  | set (c0re serves)      | absent  |
| false           | false | unset                  | absent  |

- TLS termination — separate follow-up once mara picks a story
  (self-signed-mkcert vs operator-provided certs)
- Per-agent UI routing (`/agent/<name>/`) — depends on agent base-path
  support which is a frontend lift
- Subdomain routing for `matrix.${hyperhive.domain}` — same-origin
  `/matrix/` is the v0 shape per mara ("leave everything else as is")

Closes part of #609 (matrix GUI re-rooting onto nginx); leaves the
issue open for the subdomain re-root + `.well-known/matrix/client`
piece once the multi-host story matures.
