Pull request overview
This PR fixes CLI machine-readable output (e.g. --output json) being polluted by stdlib-logging output from dependencies (notably Alembic), by making [logging] namespace_levels apply consistently to both structlog and Python’s standard-library logging loggers. It also lowers the handler threshold when needed so per-namespace verbosity can be higher than the global level without being dropped.
Changes:
- Apply
namespace_levelsto stdlib loggers by setting per-logger levels afterdictConfig, and adjust the default handler level to the most verbose configured level so overrides can take effect. - Default
alembic.runtime.pluginstoWARNINGto suppress noisy plugin-registration logs during normal CLI commands. - Add regression tests for stdlib namespace filtering and the Alembic default; update config docs to reflect behavior and namespace hierarchy.

Alembic emits autogenerate plugin registration messages at INFO during CLI startup. Those unrelated lines contaminate machine-readable command output, while warnings and errors still need to remain visible.
