docs(turn-loop): document passwordlessSudo, dashboardLinks, extraFiles, connectivity overrides

Five previously undocumented per-agent agent.nix options:

- hyperhive.user.passwordlessSudo: default-true sudo grant; note added
  with cross-reference to companion user.* options in agent-hierarchy.md
- hyperhive.dashboardLinks: declarative extra nav links on the dashboard
  card and per-agent page header; table of fields (label/url/icon)
- hyperhive.frontend.extraFiles: overlay files over the default agent dist;
  source/target semantics, constraints, collision guard, mergedDist
- hyperhive.forge.url: per-agent Forgejo base URL for tea login; default
  localhost:3000; validation note
- hyperhive.matrix.url: per-agent matrix-sdk homeserver URL; default
  localhost:8008; per-agent override use-cases (remote hive, VPN)

### `user.passwordlessSudo`
```nix
hyperhive.user.passwordlessSudo = true; # default
```
Grants the per-agent unix user passwordless `sudo` (`NOPASSWD: ALL`).
Enabled by default so claude's shell tools work for operations that
need root inside the container (`systemctl`, package managers in dev
shells, etc.) — the same privilege surface the previous root-user shape
had, now elevated explicitly rather than implicitly.
Set to `false` for agents that should be strictly unprivileged.
Any tool invocation that needs root then fails loudly with the standard
sudo rejection rather than silently succeeding — easier to audit.
`hyperhive.user.uid`, `hyperhive.user.gid`, and
`hyperhive.user.name` are the companion options; see
`docs/agent-hierarchy.md` — "Harness systemd unit shape" for the full
`user.*` surface.
### Dashboard links
```nix
hyperhive.dashboardLinks = [
{ label = "Stats"; icon = "📊"; url = "http://localhost:9001/stats"; }
{ label = "Scratchpad"; url = "http://localhost:8080"; }
];
```
Declares extra navigation links that appear on the agent's dashboard
card and in the per-agent page header alongside the built-in forge /
config / container links. Each entry has:
| Field | Required | Description |
|-------|----------|-------------|
| `label` | yes | Display text shown in the icon strip tooltip and meta-nav. |
| `url` | yes | Absolute URL — may include a different port (the dashboard renders it as a plain anchor). |
| `icon` | no | Emoji or short glyph prefix. Defaults to empty string. |
The list is written to `<state>/hyperhive-dashboard-links.json` by a
one-shot systemd unit at container boot. `hive-c0re` reads the file on
each container-view snapshot and attaches the links to the agent card
(`kind = External`) without any code change. Omitting the option
(default empty) produces no extra links.
### Custom static files
```nix
hyperhive.frontend.extraFiles = {
"games/bitburner" = {
source = ./bitburner-dist; # path relative to agent.nix
# target defaults to attribute name: "games/bitburner"
};
"my-page" = {
source = ./my-page.html;
target = "my-page.html"; # explicit override
};
};
```
Layers additional files over the default per-agent web UI dist. Each
attribute defines one overlay entry:
- **`source`** — a Nix path (file or directory) copied into the merged
static tree. Evaluated at nix build time; the resulting derivation is
pointed at by `HIVE_STATIC_DIR`.
- **`target`** — destination path within the merged tree, used as both
the served URL prefix (`/<target>/…`) and the on-disk layout.
Defaults to the attribute name. Forward slashes create nested layouts
(`"games/bitburner"` serves at `/games/bitburner/…`).
Constraints: `target` must start with an alphanumeric or `_` and
contain only alphanumerics, `_`, `.`, `/`, `-`. `..` segments are
rejected by a config assertion. The merge step refuses to overwrite
files already present in the default dist — pick a target name that
does not collide with existing paths (`static/`, `index.html`, etc.).
The default dist ships at `hyperhive.frontend.dist` (the
`hyperhive-frontend` package output, read-only). To replace the
entire UI rather than layer on top, override `frontend.dist` directly.
### Connectivity overrides
Two `hyperhive.forge.*` / `hyperhive.matrix.*` options override where
the per-agent daemons connect. Both rarely need changing on a standard
single-host deploy, but are useful for multi-hive or custom-network
setups.
```nix
hyperhive.forge.url = "http://localhost:3000"; # default
hyperhive.matrix.url = "http://localhost:8008"; # default
```
**`hyperhive.forge.url`** — base URL of the Forgejo instance. Used by
a one-shot boot unit that runs `tea login add --url <url> --token
$(cat $HYPERHIVE_STATE_DIR/forge-token)`, making `tea` and
`hive-forge` work without an extra auth step. The unit is a no-op
when `forge-token` is absent. Override when the agent should connect
to a Forgejo on a different host or port (e.g. a swarm peer's forge).
Validated: must be an `http://` or `https://` URL or the empty string.
**`hyperhive.matrix.url`** — homeserver URL used by
`hive-matrix-daemon` when connecting via the matrix-sdk. Default
points at the in-host tuwunel (`localhost:8008`), reachable over the
host loopback in shared-netns mode. Override per-agent when an agent
should talk to a different homeserver — for example a remote hive's
tuwunel reached over a VPN, or an external Matrix server for a
federation-only agent.
