The previous take put a shared NavLink wire type in hive-sh4re and
duplicated the link-building logic across crates. Per @mara on #326:
that doesn't fit the eventual frontend/backend split goal (#273).
The agent backend is the natural source of truth for what links its
own page exposes; hive-c0re just passes the list through to the
dashboard.
* hive-ag3nt/src/web_ui.rs: agent_links now also serves the
config-repo link + reads agent-declared dashboardLinks extras
from {state_dir}/hyperhive-dashboard-links.json. AgentLink gains a
kind enum (Container | Forge | External) so the frontend can build
the right href no matter which surface is rendering. The host
header is no longer used — URLs are paths for Container/Forge,
absolute for External.
* hive-c0re/src/dashboard.rs: new GET /api/agent/{name}/links route,
a same-origin proxy that fetches the agent's /api/state and
forwards just the links field. No shared wire type — hive-c0re
treats the payload as opaque JSON (serde_json::Value). All failure
modes degrade to an empty list so the dashboard still renders.
* hive-c0re/assets/app.js: container card head row gets an async-
populated icon-only nav strip from the proxy. The hardcoded stats
link, the standalone config-repo trigger, and the extras block are
gone. The deployed:<sha> chip stays — the agent harness can't know
its own deployed sha, so this chip is how the operator sees what's
live alongside the agent's (root-only) config link.
* hive-ag3nt/assets/app.js: agent page meta-links rendered via
el() / textContent (DOM build) so agent-declared icon / label / url
strings never reach innerHTML. kind-based href resolution mirrors
the dashboard side.
* docs/web-ui.md: dashboard + per-agent sections updated for the new
architecture.
Closes#262.
