Review Comment:
   This default is mutable and the existing auto-bucket regression suite still 
restores it to the old value. In 
`regression-test/suites/autobucket/test_autobucket.groovy`, after setting 
`autobucket_min_buckets` to `5`, lines 64-65 reset it with `ADMIN SET FRONTEND 
CONFIG ('autobucket_min_buckets' = '1')`. Regression suites share the same FE 
process, so after that suite runs the cluster is left with min buckets = 1 
instead of this new default of 3, which can mask this PR's behavior and pollute 
later auto-bucket tests. Please update the test to restore `3`, or preferably 
save and restore the previous value, and adjust/add coverage for the new 
default.
