Other changes: - Always display first start dialog if privacy options are unset (e.g. if the user closed GPT4All without selecting them) - LocalDocs scanQueue is now always deferred - Fix a potential crash in magic_match - LocalDocs indexing is now started after the first start dialog is dismissed so usage stats are included Signed-off-by: Jared Van Bortel <jared@nomic.ai>
