Review thread on #136050 (agent/conversation_compression_telemetry.py,
"Refusals inflate batch counts"). Since #135807 every exit of
`compress_context` (blocked by a guard, skipped, aborted, refused) logs one
`context compression attempt telemetry:` line, and
`scripts/micro_compaction_report.py` counted every such line as a batch
compaction. Keep only records whose `commit_status` is `committed`.
