Subject: [PATCH] publish(task 16): check-subcommand (pre-flight-validation)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

runCheck(config) prüft vor jedem publish-run:
  - bunker-signer erreichbar und pubkey matcht AUTHOR_PUBKEY_HEX
  - kind:10002 outbox-liste enthält mindestens 1 write-relay
  - kind:10063 blossom-liste nicht leer, alle server antworten auf
    HEAD / (405 wird toleriert — blossom-server erlauben oft kein HEAD)

liefert { ok, issues }. printCheckResult() druckt ✓ oder ✗ + liste.
