Josep Piguillem e656222b54 feat: public projects, project deletion and sagas 
Public projects:
- Project.isPublic (create/update, owners and admins). Anyone can read a
  public project without a token: project, board, tickets, comments,
  history, releases, activity, tracking and statistics, over GraphQL and
  REST. Writes stay for members (401 anonymous, 403 outsiders).
- @OptionalAuth() / @ApiOptionalPireonAuth(): anonymous callers allowed,
  invalid tokens still rejected. ReadAccess lets anonymous viewers read
  public projects only; linked tickets are filtered by visibility.
- publicProjects (GraphQL) and GET /api/explore/projects (REST).
- Web: «Explorar» page, project pages open without a session (read-only
  notice, sign-in hints), public badge, visibility switch in settings,
  no realtime subscriptions without a session.

Project deletion:
- Owner only, confirming the key (deleteProject / DELETE
  /api/projects/{project}?confirm=KEY). The key is freed; the read model
  drops the project and members are notified (web goes home).

Sagas (run by the EventsBridge after projections, durable and ordered):
- ProjectDeletionSaga: project deleted → delete its tickets and releases;
  ticket deleted → purge its comments and drop links from other tickets.
- ReleaseArchivedSaga: unfinished tickets leave an archived release.
- UserDeactivatedSaga: the Pireon webhook records UserDeactivatedEvent in
  the event store (EventRecorder); the tracker unassigns that user's open
  tickets as the system actor.
- Internal idempotent commands; domain refusals are logged and skipped,
  concurrency conflicts retried. Affected streams come from the event store
  (TrackerStreamsRepository).

Tests: domain lifecycle specs, saga specs run like the bridge, facade
tests, e2e for public access, cascade deletion, archived releases and
deactivation webhook. Docs, READMEs, schema.gql/openapi.json and Word/PDF
updated.

api-tracker-application

Casos de uso del tracker (CQRS).

  • Import: @task-stream/api/tracker/application
  • Capa: application · Tags: scope:api-tracker, type:application

Contenido

  • Services: ProjectsService, IssuesService, CommentsService, ReleasesService, ChangesService (subscriptions), WorkflowsService (workflow de cada proyecto para presentar tickets, con una caché de 2 s).
  • commands/: un fichero por command y otro por handler; cargan con WriteAccess (rehydrator) y guardan con commitAndWait().
  • queries/: un fichero por query y otro por handler; leen de los puertos Find*Repository y comprueban el acceso (ReadAccess: miembros, o cualquiera si el proyecto es público; viewerId null = anónimo); SearchMyIssuesQuery y GetUpcomingReleasesQuery cruzan todos los proyectos del usuario («Mi trabajo»).
  • event-handlers/: proyecciones (@EventsHandler) hacia el read model (incluida la línea temporal de cada ticket), notificaciones en tiempo real y feed de actividad.
  • sagas/: ProjectDeletionSaga (cascada al borrar un proyecto y sus tickets), ReleaseArchivedSaga (los tickets sin terminar salen de una release archivada) y UserDeactivatedSaga (desasigna los tickets abiertos de un usuario que Pireon desactiva). Las ejecuta el EventsBridge; sus comandos son internos e idempotentes. Tests en sagas.spec.ts.
  • analytics/: estadísticas y burnup calculados con funciones puras sobre la línea temporal (con tests).
  • ports/: lookups de escritura, Find*, UpsertMaterialized*, ReleaseIssuesRepository, ChangeFeed, UserDirectory.
  • TrackerApplicationModule.withInfrastructure(...).
