docs: align spec + dependency-flow with ADR-015

Three follow-up corrections from the docs audit:

- vertical-feature-spec § 13 dropped the events/jobs bullet from the
  "Out of scope (deferred)" list — they shipped, the bullet didn't
  belong there. The spec already mentions ADR-015 elsewhere (§ 4
  optional folders).

- vertical-feature-spec § 14 success criterion replaced "Any
  cross-feature import fails pnpm lint" with the post-ADR-015 reality:
  cross-feature imports are restricted to event contracts (the feature
  boundary tag now accepts feature-tagged deps), but rule E1
  (no-handler-reexport) keeps consumer handlers / use cases /
  repositories private.

- dependency-flow now shows the resolveEventsAndJobs* step in bindAll
  and the (config, tracer, logger, bus, queue) binder signature, plus
  the // <gen:event-handlers> / // <gen:jobs> anchor lines where the
  generators inject subscribe / register calls.
