promote Bootstrap To Parameterized Log
Promotes the bootstrap log to the final parameterized log:
Workflow:
Copy the bootstrap log to the final parameterized path (if the bootstrap exists), otherwise ensure the destination file exists.
Switch Log4j2 to write to the new parameterized file (via switchActiveLogFile).
Optionally apply a new root level (via updateRootLoggerLevel).
Best-effort delete of the old bootstrap file (errors ignored).
Ordering minimizes the window where messages could land in the old file.
Parameters
params Token
Parameter token used to build the final log filename.
desired Root Level
Optional root level to apply after switching files.
