   ## Which issue does this PR close?
   
   <!--
   We generally require a GitHub issue to be filed for all bug fixes and 
enhancements and this helps us generate change logs for our releases. You can 
link an issue to this PR using the GitHub syntax. For example `Closes #123` 
indicates that this PR will close issue #123.

   - Closes #.
   
   
   ## Rationale for this change
   
   - **Reduce Dependabot PR noise without reducing coverage**  
     Grouping most *minor* and *patch* Cargo updates into a single PR keeps 
routine churn manageable while still ensuring updates are applied regularly.
   
   - **Keep riskier updates isolated**  
     *Major* version bumps can include breaking changes, so we intentionally 
**do not group major updates**. This preserves **one PR per crate** for majors, 
simplifying review, CI triage, and rollback.
   
   - **Preserve existing special handling for Arrow/Parquet**  
     - Arrow/Parquet updates are higher impact and often coordinated, so we 
keep their **minor/patch** updates grouped together for consistency.  
     - Arrow/Parquet **major** bumps are handled manually (and ignored by 
Dependabot) to avoid surprise large-scale breakage.
   
   - **Ensure `object_store` and `sqlparser` remain easy to diagnose**  
     These dependencies can have outsized downstream impact in DataFusion. 
Excluding them from the catch-all group ensures their updates land as 
**individual PRs**, making it easier to attribute regressions and bisect 
failures.
   
   - **Maintain targeted grouping where it’s beneficial**  
     Protocol-related crates (`prost*`, `pbjson*`) are commonly updated 
together, so grouping their minor/patch updates reduces churn while keeping 
changes cohesive.

   ## What changes are included in this PR?
   
   <!--
   There is no need to duplicate the description in the issue here but it is 
sometimes worth providing a summary of the individual changes in this PR.

   ## Are these changes tested?
   
   <!--
   We typically require tests for all PRs in order to:
   1. Prevent the code from being accidentally broken by subsequent changes
   2. Serve as another way to document the expected behavior of the code
   
   If tests are not included in your PR, please explain why (for example, are 
they covered by existing tests)?

   ## Are there any user-facing changes?
   
   <!--
   If there are user-facing changes then we may require documentation to be 
updated before approving the PR.

   <!--
   If there are any breaking changes to public APIs, please add the `api 
change` label.
