Implement scrp-<script_name>-<host> sender naming: notify-elazar.sh + notify-nw.sh derive scrp-$(basename caller, strip ext, - to _)-<host> and stamp it as hub sender + email From-name/subject prefix; rename direct-hub-poster scripts (evolutiva-errscan errscan-whey-cc to scrp-evolutiva_errscan-whey, llmmsg-kpi-report llmmsg-srv-cc fallback to scrp-kpi_report-whey, sweep rest). -cc/-ca reserved for real agents.
