Function log 

pub fn log(level: Level, tag: &str, msg: &str)

Log a record with the given level, tag, and msg.

This is the only entry point for structured logging. The first call transparently initialises the log directory and file sink.

Per-sink level filtering

Level	Console (default)	File (default)
Debug	✗	✗
Info	✗	✓
Warn	✓	✓
Error	✓	✓

Override with SCRIBE_CONSOLE_LEVEL / SCRIBE_FILE_LEVEL.
