docs: make the component sections executable in one pass
Expands 3.1 and 3.2 so the work can be done without re-deriving anything.

3.1 now records what 0.8.6 already fixed, separated into the ten components
that were miswired and the five that gained outputs they had been firing
undeclared, with the caveat that Map's three were converted but never confirmed
in a browser. For the 22 that remain it adds the finding that changes the
decision: all nine are pure scaffolds with no state, functions or handlers, and
five of them duplicate a component that already works -- FileUpload against
FileInput and FileUploadProgress, Toast and ToastNotifications against Toaster,
AdvancedDatePicker against DatePicker, AdvancedRangeSlider against RangeSlider.
Superseding those is a migration entry rather than new code, and leaves Chart,
TreeView, Confetti and CopyMarkup as the only ones needing to be built.

3.2 corrects the scaffold count from 23 to 28; the earlier figure used a looser
rule. Nine of the 28 are the 3.1 components, so the two items must be planned
together, and several of the rest are primitives that need only their styles
moved out of ui.css rather than any behaviour.

Also corrects the dead-output component count from 11 to 9 in both documents.

# inter-app-api-showcase
A WrNexus **workspace** — multiple apps, one gateway, interconnected.
```
inter-app-api-showcase/
wrnexus.workspace.ts # apps ↔ domains map (used by `wrnexus gateway`)
apps/
web/ # a WrNexus app → localhost, web.localhost
admin/ # a WrNexus app → admin.localhost
packages/
shared/ # @app/shared — shared code + cross-app pubsub bus
```
## Run everything (one port, routed by domain)
```bash
bun install
bun run dev # = wrnexus gateway → http://127.0.0.1:3000
```
Add the hosts to your machine (e.g. /etc/hosts):
```
127.0.0.1 web.localhost admin.localhost
```
Open `http://localhost:3000` for the web app or
`http://admin.localhost:3000` for the admin app. The ports printed for individual
apps are internal gateway targets, not public workspace URLs.
## Interconnect
- **Shared code:** import `@app/shared` in any app.
- **Runtime messaging:** `import { bus } from "@app/shared"` then
`bus.publish("tenant:created", {...})` in one app and
`bus.subscribe("tenant:*", fn)` in another (needs Redis).
- **Databases:** point apps at the same `db`/`databases` in their config.
## Add another app
```bash
wrnexus workspace add reports --domain=reports.localhost
```
