iris 0e2319d206 frontend: populate real npmDepsHash from prefetch-npm-deps
Manager approval 1b1bcca added `pkgs.prefetch-npm-deps` to my
container. Ran `prefetch-npm-deps frontend/package-lock.json` →
`sha256-MHXxkZpe/5LAhpQ76ZK94znG2noTobthjUi6iNY8/K4=`. Replaced
the `lib.fakeHash` placeholder in `nix/frontend.nix` with the real
value; updated the comment to point at the recompute command instead
of the let-it-fail workflow.

This unblocks PR #350 for merge — `nix build .#frontend` will now
succeed without the operator having to compute and patch the hash.

Refs #273.

# Hermetic build of the npm-managed frontend workspaces (see
# `frontend/README.md`). Consumes `frontend/package-lock.json` as the
# source of truth for dependency versions; `npmDepsHash` pins the
# vendor-tarball hash so a stale lockfile fails the build instead of
# silently fetching different upstream tarballs.

# Output layout (`$out`) — two subdirectories, one per surface, that
# the Rust binaries serve via `tower_http::ServeDir`:
#
# $out/dashboard/ the hive-c0re dashboard SPA assets
# index.html app.js app.js.map dashboard.css favicon.svg
# $out/agent/ the per-agent default UI (layered with
# hyperhive.frontend.extraFiles at activation time)
# index.html app.js stats.html stats.js agent.css screen.html
#
# The dashboard favicon lives outside the npm tree (`branding/hyperhive
# .svg` at the repo root) — we copy it in during the install phase so
# the served prefix has everything in one place.
