Notice the duplicated log. and it breaks the UI too.

new _instrument_bub breaks the logger key

https://github.com/bubbuild/bub/blob/main/src/bub/__main__.py#L12

# __main__.py
def _instrument_bub() -> None:
    from loguru import logger

    # the old 0 keyed handler removed
    logger.remove()
    # this logger gets assigned 1 as the handler key
    logger.add(sys.stderr, colorize=True)

https://github.com/bubbuild/bub/blob/main/src/bub/channels/cli/__init__.py#L53

    # channels/cli/__init__.py

    def _install_log_sink(self) -> int:
        with contextlib.suppress(ValueError):
            # this removes the handler with 0 as key, absent now, so fails, and silenced, making it really hard to spot
            # maybe we can call remove(), but then I'm afraid logfire instruments in the above code will break
            logger.remove(0)
        return logger.add(self._renderer.log, colorize=False, format="{level:<8} | {message}")
