iris 2a67cc0e69 nix: single-source frontend npmDepsHash into frontend/npm-deps-hash
The hash was hardcoded independently in nix/packages/frontend.nix,
nix/packages/swarm-ui.nix, and nix/checks.nix's inline
swarm-ui-typecheck derivation, all three building from the one
frontend/package-lock.json. Nothing enforced the three copies staying
in sync, and on a recent PR only some of them got updated when the
lockfile changed.

Moved the hash into a new file, frontend/npm-deps-hash (plain text, no
trailing newline, co-located with package-lock.json so it reads as
the lockfile's other half), and all three derivations now
builtins.readFile it instead of hardcoding their own copy. A lockfile
change now only needs prefetch-npm-deps + one file overwrite; the
other two derivations pick it up automatically.

Verified: nix eval against all three derivations' npmDepsHash
attribute (eval-only, not a build) confirms all three resolve to the
same value read from the one file.

{ buildNpmPackage }:
# Static build of the swarm-level UI shell (project-bootstrap scope:
# empty start page, no functionality yet — see
# frontend/packages/swarm-ui/package.json for the full rationale).
# Stack: Preact + wouter + TypeScript + JSX, a real SPA shell with
# routing/deep-links, distinct from the per-hive dashboard's
# vanilla-JS + custom-element MPA.
#
# Deliberately its OWN package, not folded into `./frontend.nix`
# (which bundles dashboard + agent into `packages.default`'s closure):
# swarm-ui is swarm-scoped, same reasoning `swarm-controller`/`swarmctl`
# already use for staying out of `daemonBins` — a hive that doesn't run
# the swarm controller shouldn't carry swarm-ui bytes in its closure.
#
# Not yet consumed anywhere: swarm-controller only serves `/health`
# today (swarm-controller/README.md) — this just makes the static
# build a buildable, packageable artifact so the wiring (once auth
# against authelia is figured out) has something to point at.
#
# Shares `frontend/package-lock.json` with `./frontend.nix` (same repo,
# same npm workspace root) — `npmDepsHash` is read from
# `../../frontend/npm-deps-hash`, the same file `./frontend.nix` and
# `../checks.nix`'s `swarm-ui-typecheck` read, so all three stay in
# lockstep automatically instead of needing 3 separate hand-edits.
# Scoped to build only the `swarm-ui` workspace (not the whole
# `npm run build --workspaces` frontend.nix runs) via an explicit
# `npm run build --workspace=…` buildPhase, so a dashboard/agent-only
# change doesn't need to rebuild (or re-review the output of) this
# derivation.
