Nit: Footnote referencing GeoParquet 1.0

1

Shall this footnote be updated, now that GeoParquet 1.1 is out? Can you now simply say that Lonboard uses GeoParquet [1.1]? https://github.com/developmentseed/lonboard/blob/033a45a0981dce3a2e9e239c6eb4a720bcb6c2b6/docs/how-it-works/index.md?plain=1#L11

Regression: From version `0.7` onwards, a parquet file without metadata but with a WKB BLOB in a column called `geometry` cannot be opened anymore

config `autoinstall_extension_repository` is only taken into account if `custom_extension_repository` is also set

### What happens? If i set the config `autoinstall_extension_repository` _without_ also setting `custom_extension_repository`, the setting is ignored. ### To Reproduce ```python import duckdb duckdb.__version__ # Outputs: # # '1.3.0' ```...

Cell magics starting with single '%' are not ignored

2

For better or worse, some systems use single '%' headers for cell magics, notably [Databricks](https://docs.databricks.com/aws/en/notebooks/notebooks-code#mix-languages), e.g. `%sql` and `%r`. I successfully used `nbQA` with `%sql` cells for a long time...

Feature Request: Support for gitleaks (or trufflehog)

2

The tools [gitleaks](https://github.com/gitleaks/gitleaks) and [trufflehog](https://github.com/trufflesecurity/trufflehog) can catch secret keys before they're checked in in git, but they don't get triggered by secrets in notebooks. Theoretically it would be a perfect...
