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.
