Ekklesia's module model has been backend-only since ADR 0001: a module
owns domain behavior and data, and every presentation concern belongs to
a surface. That prevents a module author — the person who knows the
domain — from shipping the screen that makes their module useful, and it
guarantees a module and its own UI drift apart. It also pushes toward two
codebases for one domain the moment a module needs to run standalone.

ADR 0021 replaces that rule. A module is an independently versioned
product that owns its domain behavior, data, permissions, routes,
migrations, and its own UI, hostable inside Ekklesia and — from the same
implementation — by a later standalone host. Core keeps the containing
application shell and every platform policy: authentication,
authorization enforcement, platform context, top-level routing,
navigation, global theme, error boundaries, and trusted-origin/CORS. The
module graph stays flat: modules are peers, genuine module and capability
dependencies remain the only relationships, and Dashboard folders are
presentation configuration an administrator can reorganize, never module
architecture.

This pass implements the static contract only. manifestVersion moves to
4 and entrypoints gains one optional field, ui. Version 3's
entrypoints is strict and rejects ui, so this is an incompatible
shape change and version 3 is now rejected outright rather than
reinterpreted, exactly as version 1 was by version 2 and version 2 by
version 3. Every field version 4 adds is optional, so upgrading a
backend-only manifest is a one-character edit.

Discovery resolves and validates ui under the same rules as server
and schema — package-relative, inside the package before and after
symlink resolution, a real file, compiled ESM .js/.mjs, so source
TypeScript is rejected rather than assumed to be compiled later.
Discovery stays inert: nothing imports, evaluates, mounts, or renders a
UI entrypoint, and a test proves a throwing artifact still discovers
successfully. This follows entrypoints.jobs, declared and resolved
since ADR 0006 with no runtime consumer.

The name is ui, not dashboard, because a module's UI must be hostable
by Ekklesia's shell and by a standalone host, so the contract cannot be
named after one of them; and not surface, because surfaces/* is a
separate ownership layer. No widget, route, icon, folder, menu, layout,
or standalone-metadata field is added, and tests assert the manifest
still rejects every unknown entrypoint key and offers no hierarchy field.

Deliberately unchanged: scripts/check-boundaries.ts still enforces
modules-do-not-own-ui. Relaxing that guard depends entirely on the UI
authoring model a later pass chooses, and weakening a working protection
before that decision exists would trade real coverage for nothing. A
module may therefore declare ui today only for a framework-neutral
compiled artifact, and the docs say so rather than implying otherwise.
Restart-based discovery, explicit operator-invoked migrations, and the
trusted compiled-module model are untouched — a module that ships UI is
exactly as trusted as one that does not.

No Dashboard shell, UI runtime, renderer, framework choice, navigation
registry, grouping system, standalone host, installer, hot-loading, or
feature module is added by this pass.
