iris 38aa5f77f4 frontend: guard hive-menu/hive-agent-menu connectedCallback against reconnect
Fixes hyperhive#2893: 'Element.attachShadow: Unable to re-attach to
existing ShadowDOM', crashing swarm.js's live-update render path.

A custom element's connectedCallback fires again on a same-document
*move* (insertBefore/append repositioning an already-connected node
runs the removal + insertion steps for its whole subtree), not just
on a fresh mount. swarm.js's row-fingerprint cache reuses + reorders
existing <li> subtrees on live updates -- reordering an unchanged,
cached row moves its already-initialised <hive-agent-menu>/<hive-menu>
without ever really detaching it from the document, so connectedCallback
re-runs full setup on an instance that's already set up. attachShadow()
throws unconditionally if the host already has a shadow root, and
HiveAgentMenu's unconditional child-menu creation would have appended a
second <hive-menu> on top of the first, doubling the dropdown, once the
shadow-attach crash itself was out of the way.

Both connectedCallbacks now bail early if already initialised
(shadowRoot present / _menu already built). Reproduced the crash and
duplicate-menu bug with an unguarded control copy of both files driven
via headless Chromium (simulating the exact row-reorder move), then
confirmed the guarded version throws nothing, keeps the same shadowRoot
object identity across the move, and doesn't duplicate the dropdown.

hyperhive frontend

npm workspaces project for the hyperhive browser-facing assets:

  • packages/shared/ — shared modules used by both surfaces (terminal pane, Catppuccin palette + body typography).
  • packages/dashboard/ — the hive-c0re dashboard SPA.
  • packages/agent/ — the per-container web UI (default agent page, stats, screen).

Build

npm install            # one-off; uses the checked-in package-lock.json
npm run build          # builds every workspace into packages/*/dist/

The Rust binaries serve packages/dashboard/dist/ and packages/agent/dist/ via tower_http::ServeDir at runtime; the build derivation is wired up in nix/modules/frontend.nix. Per-agent additions are layered on top of the default agent dist via the hyperhive.frontend.extraFiles option in agent.nix.

Why npm + esbuild

  • Hermetic: dependencies vendored via the checked-in lockfile; buildNpmPackage in nix uses it as the source-of-truth so the output is reproducible without network access at build time.
  • esbuild: vanilla-JS bundler, no framework runtime overhead. Each workspace's build.mjs is ~30 lines.
  • Single-PR migration: see issue #273 for the design proposal and the four-commit shape (npm scaffold → nix derivations → container plumbing → Rust cutover).
