Calls every registered handler with no arguments inside
tryCatch, reporting which entries can be invoked safely.
Intended to be called from CI smoke tests.
Examples
if (FALSE) { # nzchar(Sys.getenv("MORIE_RUN_FULL_SMOKE"))
# \donttest{
# Invokes EVERY registered command handler -- some fetch live data over the
# network -- so this is a smoke test, not a quick example. Opt in with
# MORIE_RUN_FULL_SMOKE=1.
str(stat_bridge_verify(), max.level = 1)
# }
}
