Removes the *.hex/maps_cache gitignore rule (explicit user call, reversing the earlier no-redistribution stance) so the official TuneECU catalogue maps, derived SAI/O2-delete composites, and the checksum/composition tooling are actually available to pull up on a phone browser when using the real TuneECU app. Also folds in tonight's KWP2000 fixes (TesterPresent keep-alive, connect-failure cleanup, slow-init StartCommunication fix) and the accumulated research docs.
