- `@kanta.logemit` handler for completely customizable logging output, with `LogEvent` structure and `kanta.tty.Line` helper to create colorized text and fixed width fields - `configure_logging(diff=False)` to disable diff display globally (supplementing per-transaction `logdiff=False`) - `transaction(extra: Any = ...)` for passing extra strings or custom metadata to logs - `@kanta.clock` to provide user controlled clock for deterministic database outputs - Added a demo script that shows basic functions, migrations, logfmt etc.
