Runners were POSTing a debug log to the supervisor for every log line -
one request per line, unbatched and unconditional. The supervisor
already has a `SEND_RUN_DEBUG_LOGS` toggle (off by default) that
discards them on receipt, but the runner fired the request regardless,
so the traffic hit the supervisor either way.
This gates the send at the source. The runner now reads
`TRIGGER_SEND_RUN_DEBUG_LOGS` (off by default, injected by the
supervisor from its existing `SEND_RUN_DEBUG_LOGS` setting) and skips
the POST entirely when disabled. Local log output is unchanged. Dev runs
use a separate path and are unaffected.
