JulioFerreiraDev/SWL2001: v4.8.0-sf10-fallback.1 - SF10 fallback supervisor

This release adds an SF10 fallback supervisor for LoRaWAN end-devices based on consecutive ACK failures, built on top of SWL2001 v4.8.0 (LoRa Basics Modem examples). The algorithm monitors TX completion status (SMTC_MODEM_EVENT_TXDONE / SMTC_MODEM_EVENT_TXDONE_CONFIRMED) and whether the last uplink was requested as confirmed (last_uplink_confirmed_requested). After a threshold of consecutive missing ACKs, it temporarily forces an SF10-oriented ADR profile. The device returns to the default network-controlled ADR after a fixed usage window. Changed file: lbm_examples/main_examples/main_periodical_uplink.c This artifact is intended to support reproducibility of the experimental methodology.
