Phase 2 sub-commit 5: convention test passes, skeleton walkthrough, phase 2 closed

Runs `make:bridge:resource Todo` against the skeleton, then `make:migration`
+ `doctrine:migrations:migrate`, and verifies the round-trip end-to-end:

  - POST /api/todos creates a row with a UUIDv7 id
  - GET /api/todos returns the row
  - Mercure dual-publishes:
    - app://model/todo (collection topic)
    - app://model/todo/{uuid} (entity topic)
  - The published envelope shape matches PLAN.md §4 exactly:
    {op:"upsert", id:..., version:..., data:{...}, correlationKey:"..."}
  - correlationKey echoes the request's Idempotency-Key, ready to be
    matched by ReactiveListModel's pending state on the QML side.

Generated files committed as the regression baseline (Phase 3 will add
a CI check that re-running the maker reproduces these byte-for-byte):

  - framework/skeleton/symfony/src/Entity/Todo.php
  - framework/skeleton/symfony/src/Controller/TodoController.php
  - framework/skeleton/symfony/migrations/Version20260502004612.php
  - framework/skeleton/qml/TodoList.qml

framework/skeleton/README.md captures the three-command flow plus a
curl walkthrough so future readers can reproduce. Phase 2 done.
