teknium1 314076ca63 fix(messaging): hermes send reports dropped MEDIA attachments instead of success:true
filter_media_delivery_paths kept only the survivors, so a MEDIA path that did
not exist on the host (or was denied by the delivery policy) vanished with a
host-side warning while the caller got success:true / exit 0 and booked a
delivery that never happened. _validated_delivery_path and
filter_media_delivery_paths take an optional `dropped` list that collects
{path, reason}; send_message_tool passes it and, when anything was dropped,
returns success:false + partial_success:true + media_dropped + an error line,
which hermes send already turns into a non-zero exit. Slim redo of #115913
(@fangliquanflq): same payload shape, out-parameter instead of a wrapper pair.
