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.
