feat(deno): developer-ecosystem workspace finalisation — root deno.json with workspace field (STEP 7 closeout) (#100)

## Summary

Completes the **STEP 7 workspace finalisation** acceptance criterion (1)
for `developer-ecosystem` from hyperpolymath/standards#275: add
`deno.json` at repo root with `workspace` array listing all 40
sub-projects with their own `deno.json`.

Per the STEP 6 closure (hyperpolymath/standards#273), the
per-sub-project migrations were already landed via the cross-cutting
workflow-modernisation + tooling sweeps over April-May 2026 (19 of 23
in-scope manifests paired with `deno.json`; the remaining 4 are
dependency-shim Class C npm-publishable consumer artifacts where
Deno-native exposure isn't a priority). The workspace-root coordination
is the closeout task per STEP 7's body.

## Workspace member breakdown (40 members)

| Tree | Members | Notes |
|---|---|---|
| `affinescript-ecosystem/` | 3 | `affinescript-deno-test`,
`rattlescript/affinescript/packages/{affine-js,affine-ts}` |
| `aggregate-library` | 1 | Always Deno-native |
| `cadre-router` + nested | 2 | top-level + `tea-router-pkg` |
| `cadre-tea-router` | 1 | top-level peer |
| `coq-ecosystem/coq-jr` | 1 | Class A migrated |
| `deno-ecosystem/projects/` | 2 | `beamdeno`, `deno-bunbridge` (always
Deno-native) |
| `rescript-ecosystem/` | 29 | packages/, cadre-router*,
cadre-tea-router, idaptik-rescript13-staging*,
rescript-{deno-starter,dom-mounter,evangeliser,tea,vite} |
| `v-ecosystem/v-deno` | 1 | V-lang Deno binding |

Top-level tasks `build-all`/`test-all`/`fmt`/`lint` delegate to
per-member tasks via `deno task --recursive`.

## What is intentionally NOT included

- **rescript-ecosystem/rescript/** — upstream-fork carve-out (22
manifests) covered by hypatia `:nodejs_detected` `rescript/`
`path_allow_prefix`
- **rescript-ecosystem/packages/core/compiler-source/** — vendored
upstream rescript snapshot (45 manifests, separate version line
`13.0.0-alpha.1` vs `alpha.3` of the active fork)
-
**affinescript-ecosystem/.../editors/{vscode,tree-sitter-affinescript}/**
— VSCode + tree-sitter Class C carve-outs
- **4 dependency-shim Class C npm-publishable manifests** —
`affinescript-vite`, `rescript-grpc-runtime`, `rescript-string-power`,
`rescript-vite-config` — declared in STEP 6 closure as residual

After this PR merges, developer-ecosystem satisfies acceptance criterion
(1) of hyperpolymath/standards#275; the remaining residuals are
out-of-scope per the umbrella body's `Out of scope` carry-forward.

## Test plan

- [ ] CI green (additive only — no existing manifest touched)
- [ ] `deno task --version` recognises the workspace root
- [ ] Hypatia `:nodejs_detected` scan stays quiet (zero
`package-lock.json` in repo)

Refs hyperpolymath/standards#275 (this completes the developer-ecosystem
portion).
Refs hyperpolymath/standards#253 (umbrella npm → Deno migration).
Refs hyperpolymath/standards#273 (STEP 6 closeout — substantially-done
declaration).
