- Facilitates #507, #642. - Plumb logger with logger option access into every command. - StderrLogHandler allows logging to be enhanced for ANSI color mode for log levels, JSONL log output, replacing `--debug` with `--level level`. - Global logger is now just an Application.swift fileprivate only used for initial args processing. - Log with timestamp at debug and trace level. - Metadata output is crude at present; we can refine this in a follow-up.
