Excessive logging on startup

go-java-launcher spams out a wall of text every time I run my app, sample included below.

Could we disable this logging by default? This would improve the signal-to-noise ratio of log files, especially because these lines seem to be most useful to devs of go-java-launcher and aren't really useful to an app developer.

One option would be to follow rust's lead and only output logs if an environment variable is set, such as DEBUG_LOG.

The worst offenders seem to be in launcher.go: https://github.com/palantir/go-java-launcher/blob/405cb8ec1524a5c9daaa2a92d85311525ef29e8d/launchlib/launcher.go#L72. It's also unfortunate that the first line printed begins with the word "Failed", despite the app functioning exactly how I intended.

sample logs:

Start with the logging and startup output referenced in launchlib/launcher.go around line 72 and go-java-launcher/main.go around line 35. Trace how these messages are emitted and decide how the requested default quiet behavior should work, including the misleading “Failed” prefix. Done means normal launches no longer produce the reported wall of diagnostic output by default, while the issue’s proposed opt-in behavior is addressed.
