feat: add Dashboard navigation as presentation configuration
Phase 6D pass 1. The shell's navigation was a flat list of module ids, which
is not a usable experience — and the obvious fix carries an obvious trap.
Letting a module declare its folder, or modelling "Media" as something
Livestream and Video belong to, turns a rendering preference into
architecture: a folder becomes an owner, membership starts to look like a
dependency, and the flat module graph acquires a hierarchy nobody decided on.

So the rule comes first: a Dashboard group is a label on a rendering bucket.
No manifest, no version, no artifact, no API, no lifecycle; nothing depends on
it. Livestream depends on Video because it calls Video's functionality, and
that orders startup. Livestream is shown under Media, and that orders nothing.
No parent module, child module, owning module, or group-derived dependency
appears anywhere in the contracts.

No manifest change and no version 5. `manifest.name` has been required since
version 1 and already is the module's product identity, so the shell renders
"Livestream" instead of `livestream` with nothing added. `suggestedGroup` is
deliberately deferred rather than shipped: it would force a hard
manifest-version cutover for a hint, and its only correct semantics needs
initialization logic that risks a suggestion overwriting an administrator's
decision. Defaulting and ownership are different things.

Two Core tables (migration 0003) hold groups and placements — server-side,
because a church configures its Dashboard rather than one browser;
platform-global, because no organization model exists to scope them to.
`group_id` is `on delete set null`, so deleting a group ungroups its modules
and a dangling reference is impossible. `module_id` carries no foreign key,
because modules are packages rather than rows, so a placement for an
uninstalled module is retained and restores its position on reinstall.

`resolveDashboardNavigation` is a pure function of configuration plus the
mountable set: an unplaced module is ungrouped and visible with no
initialization write, an absent module renders nothing, empty groups are kept,
and ordering is total with the module id as final tie-break.

`GET /api/v1/dashboard/navigation` returns the resolved view, layered on top of
the host-neutral module UI inventory rather than merged into it — each generic
descriptor is embedded untouched, so a standalone host never inherits Dashboard
semantics. Reading needs the permission the inventory already needs; organizing
needs the new platform permission `core.dashboard.navigation.manage` through a
narrow, idempotent, closed-validation mutation contract. No editor UI.

The flatness rule is executable: a test discovers real fixtures with a genuine
dependency, arranges them four ways including both in one folder and the
dependency inverted in presentation, and asserts discovery order, dependency
declarations, and the module set stay byte-identical. The end-to-end test
organizes a real installation through the real API, mounts a module from inside
a group, moves it, and asserts the navigation entry is byte-identical across the
move and still mounts the same artifact.

The shell's client for the generic inventory became dead code and was removed
rather than kept speculatively; the endpoint itself is unchanged.

# Contributing
Ekklesia is being built in verified, reviewable phases. Changes should preserve the dependency
boundaries described in [repository-boundaries.md](docs/architecture/repository-boundaries.md).
Before opening a change, run:
```bash
pnpm verify
```
Migration-runner changes also require the disposable live PostgreSQL suite:
```bash
pnpm test:migrations:integration
```
See the [testing guide](docs/development/testing.md) for the distinction between unit and live
evidence and for credential-safe troubleshooting.
When adding or changing a module manifest, also run `pnpm modules:validate` directly for focused,
path-aware discovery errors. It is included in `pnpm verify`.
If Docker is available, also validate the development infrastructure:
```bash
pnpm infrastructure:config
```
## Package rules
- Use strict TypeScript for production packages.
- Expose supported entry points through package `exports`; do not import another package's
private source paths.
- Use `workspace:` ranges for internal package dependencies.
- Modules own their own UI and author it in React and TypeScript (ADR 0022). A module package may
contain `.tsx` and depend on `react`, `react-dom`, and `@ekklesia/module-ui-sdk`. Every other UI
framework, `.jsx`, stylesheets, and other presentation formats remain rejected by
`pnpm boundaries`. UI source lives at `src/ui/index.tsx` and `pnpm build` compiles it to the
artifact the manifest declares, via `@ekklesia/module-ui-build` (ADR 0023) — module authors write
no bundler configuration. Styling is React inline style objects only for now, and no host mounts a
UI entrypoint yet.
- Module UI reaches its host only through `@ekklesia/module-ui-sdk` — never
`@ekklesia/module-ui-host`, which is the host-side loader — and asks the host for its own
API by relative path — never by constructing `/api/v1/modules/<id>/...`, which is Ekklesia's
private deployment detail and would break standalone hosting.
- The containing application shell, navigation, global theme, and platform policy belong to Core and
the host application, never to a module. Ekklesia's own shell is `surfaces/shell`; it discovers
installed module UIs through `GET /api/v1/module-ui` and mounts them with
`@ekklesia/module-ui-host`, and it statically imports no module (ADR 0026).
- Dashboard groups are presentation configuration, never module structure. Do not add a parent
module, child module, owning module, or group-derived dependency: real module relationships are
the dependency contract's job alone, and grouping must never influence discovery, dependency
ordering, startup, or authorization (ADR 0027). A module declares its display name
(`manifest.name`); the Dashboard owns where it appears.
- A surface is browser code. It may depend on browser-safe shared roles only — never
`@ekklesia/contracts` or `@ekklesia/module-sdk`, whose type graphs pull Node's globals into the
browser — and it reaches the server over HTTP.
- Add or update tests when changing a contract or architectural rule.
- Record major architectural changes in an ADR rather than burying them in an implementation.
Runtime registries and aggregate schemas will be produced by later phases. Do not add a manually
maintained feature-module registry; discovery starts from validated `ekklesia.module.json` files.
