fix(cli): skip large JSON inspection outside debug mode

[suntaoathome]

Logger.debugLargeJson() logs that message inspection is skipped when DEBUG is disabled, but it does not return. It still recursively traverses, serializes, and writes the payload to disk. This adds the missing early return and a regression test. Debug-mode behavior is unchanged.

Proof

A production daemon log created before the fix contained both the skip marker and the supposedly skipped socket payloads:

skip_markers=83946
socket_update_payloads=83632

With the fix running:

skip_markers=2694
daemon_environment_payloads=0
socket_update_payloads=0

The regression test uses an enumerable getter that throws if the payload is inspected. The call now returns without touching it.
