Slice 1 polish: archive dormant code, merge work-os into primitives, add futures

- Archive dormant apps (daemon, desktop, native, tui) and superseded
  packages/server into repos/ for reference
- Archive 21 dead web components (chat page shell, work-os cluster, strays)
  into repos/web/; keep reused message-rendering primitives in components/chat
- Merge @code/work-os into @code/primitives; work.ts absorbed via ./work
  subpath and barrel export; update all four importers
- Add docs/futures.md tracking audio/video (blocked at Flue + provider),
  web layout cleanup, and message rendering quality
- Repoint dev:zopu script to @code/agents (the live Flue server)
- Note repos/ reference-code convention in AGENTS.md
