* glog: add JSON structured logging mode Add opt-in JSON output format for glog, enabling integration with log aggregation systems like ELK, Loki, and Datadog. - Add --log_json flag to enable JSON output at startup - Add SetJSONMode()/IsJSONMode() for runtime toggle - Add JSON branches in println, printDepth, printf, printWithFileLine - Use manual JSON construction (no encoding/json) for performance - Add jsonEscapeString() for safe string escaping - Include 8 unit tests and 1 benchmark Enabled via --log_json flag. Default behavior unchanged. * glog: prevent lazy flag init from overriding SetJSONMode If --log_json=true and SetJSONMode(false) was called at runtime, a subsequent IsJSONMode() call would re-enable JSON mode via the sync.Once lazy initialization. Mark jsonFlagOnce as done inside SetJSONMode so the runtime API always takes precedence. * glog: fix RuneError check to not misclassify valid U+FFFD The condition r == utf8.RuneError matches both invalid UTF-8 sequences (size=1) and a valid U+FFFD replacement character (size=3). Without checking size == 1, a valid U+FFFD input would be incorrectly escaped and only advance by 1 byte, corrupting the output. --------- Co-authored-by: Chris Lu <chris.lu@gmail.com>
