atlas ae9ca4331e swarm: keep an agent's terminal rows and replay them on attach
swarm-controller now creates `term-main-<agent>` for every live agent, in
the same one-minute pass and with the same config style as
`term-sub-<agent>` (#4897): subjects `$SWARM.term.<agent>` only, max_age
24h, max_bytes 64 MiB, discard Old, max_message_size from the queue's
max_payload. An existing stream is opened as it is. The agent keeps its
plain publish on `$SWARM.term.<agent>` and gets no JetStream subject.

`GET /api/agents/{name}/term/stream` creates an ephemeral push consumer on
that stream starting 100 rows back, so a swarm-ui terminal opens with
recent history and then follows new rows, in order, from one
subscription. Each SSE event carries the row's stream sequence as its id,
and a reconnect's Last-Event-ID resumes after it. Without the stream the
route falls back to the live core subscription it used before.

The stream is `term-main-<agent>`, not `term-<agent>`: an agent may be
named `sub-x`, whose `term-<agent>` would be agent `x`'s subagent stream.
Its one literal subject cannot match `$SWARM.term.<agent>.sub.>`, which
needs more tokens, so the two streams never overlap.

The reader gains `$JS.API.CONSUMER.CREATE.*.*.$SWARM.term.*`, the
extended create form whose last tokens are the consumer's filter. Checked
against nats-server 2.14.4, the trailing `*` also admits a literal `*` or
`>` filter, so a consumer under it reaches any terminal row, main or
subagent; those are rows the reader already subscribes to and reads with
`STREAM.MSG.GET.*`.

Closes #4826

hyperhive frontend

npm workspaces project for the hyperhive browser-facing assets:

  • packages/shared/ — shared modules used by every surface (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).
  • packages/swarm-ui/ — the swarm-level operator UI shell (hives, agents, jobs, issue-report pages).

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; nix/packages/frontend.nix wires up the build derivation. The services.hyperhive.agent.frontend.extraFiles option in agent.nix layers per-agent additions on top of the default agent dist.

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: agent and swarm-ui are Preact apps; dashboard is a vanilla-JS + custom-element MPA with a few Preact-rendered pages (builds.js, swarm.js); shared holds both kinds of module. No framework runtime beyond Preact where it's used. Each workspace's build.mjs is a short esbuild script.
  • Single-PR migration: see the tracked design proposal and the four-commit shape (npm scaffold → nix derivations → container plumbing → Rust cutover).
