- Add delayed_action_state_t in the UE context for ongoing delayed action - Move delay check and timer re-enqueue to rrc thread in rrc_gNB.c (rrc_delay_transaction) - Call delay before NGAP setup/release handlers; remove local delay logic from rrc_gNB_NGAP.c - Clear on RRCReconfigurationComplete (reset_delayed_action) Closes #960
