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.
