Subject: [PATCH] Drop OpenTelemetry's per-instrumentation install lines from
 boot output

Every console, web, and job boot printed ~15 INFO lines confirming each
instrumentation installed, burying the useful output. Filtering only that
message keeps OTel's other INFO, WARN, and ERROR lines visible.
