v0.2.0 (8/N): make:bridge:read-model maker

Implements PLAN.md §8's fourth makers-table row. Read-models are
server-side projections — joined fetches, aggregates, denormalised
views — that QML reads without going through a writable
#[BridgeResource]. The maker emits:

  - src/ReadModel/<Name>ReadModel.php — query service stub injecting
    EntityManagerInterface; user fills query() with DQL / QueryBuilder
    / raw SQL as fits.
  - src/Controller/<Name>Controller.php — single GET handler at
    /api/<kebab-plural>, just normalises the read-model output to JSON.
  - {qml_path}/<Name>List.qml — ReactiveListModel bound to the route,
    deliberately no Mercure topic.

The "no topic" choice is the design call worth documenting: read-models
are queries, not reactive resources, and pretending otherwise would
either auto-publish stale aggregates on every entity change or require
the user to invent invalidation logic in the listener. Better: pair
the read-model with `make:bridge:event` and call refresh() from the
QML event-handler when the underlying data really changes.

Naming convention: kebab-PLURAL routes (`/api/todo-summaries`) for
consistency with REST list semantics; resource path stays singular
under `src/ReadModel/`.

Wired into services.yaml's when@dev block. Three new snapshot
baselines (TodoSummaryReadModel.php / TodoSummaryController.php /
TodoSummaryList.qml) plus runner extension. All 14 maker outputs
verify on the committed state.

 - **`Maker\Support\Naming`** — `camelTo($name, $separator)` helper. Replaces inline `preg_replace('/(?<!^)[A-Z]/', $sep.'$0', $name)` regex copies (BridgeResourceMaker emits `_`-joined route plurals, BridgeCommandMaker emits `-`-joined kebab slugs).
 - **`make:bridge:resource --with-dto` opt-in.** Generates `Create<Name>Dto` + `Update<Name>Dto` under `src/Dto/` alongside the controller, and the controller dispatches via `#[MapRequestPayload]`. Closes the input-validation gap from the audit: malformed JSON, missing required fields, or `#[Assert\NotBlank]` violations now produce RFC 7807 `application/problem+json` automatically (Symfony's `RequestPayloadValueResolver`) — no more `if (isset($data['title']))` boilerplate, no silent type coercion. Update DTOs use nullable defaults so PATCH callers send only the fields they want changed. Without `--with-dto` the legacy template still ships unchanged. Maker fails loud if `symfony/validator` isn't autoloadable. Skeleton + example/todo composer.json pull `symfony/validator` so scaffolded apps work out of the box. Snapshot test exercises both modes.
 - **`make:bridge:event <Name>` maker.** Generates a domain-event class (`src/Event/<Name>Event.php`, readonly value object), a subscriber (`src/EventSubscriber/<Name>Subscriber.php`) that republishes via `PublisherInterface` on `app://event/<kebab-name>`, and a QML stub (`{qml_path}/<Name>EventHandler.qml`) that listens via `MercureClient` and re-emits as a typed `signal`. Closes the third row of PLAN.md §8's makers table; pairs with the existing `make:bridge:resource` / `command` / `window` makers so domain events have a one-command path from PHP through to QML.
+- **`make:bridge:read-model <Name>` maker.** Generates a query-only projection: `src/ReadModel/<Name>ReadModel.php` (query service stub injecting `EntityManagerInterface`), `src/Controller/<Name>Controller.php` (single GET handler at `/api/<kebab-plural>`), and `{qml_path}/<Name>List.qml` (`ReactiveListModel` bound to the route, deliberately *no* Mercure topic — read-models aren't auto-reactive; invalidation is event-driven via `make:bridge:event`). Closes the fourth row of PLAN.md §8's makers table.
