6215: fix error return code in commit
fixes commit to return an error when there is an error processing result rows
6212: Add dolt_schema_diff table function
dolt_schema_diff will return the schema diffs between refs and optionally will filter those changes to a specific table.
This is a new table function that provides us with the information we need for dolt diff.
The original PR for this change was accidentally merged too early. The comments from that PR have been integrated into this change.
6203: Bug fixes for resolving the default DB name to the correct branch, was broken in several cases

1847: Fix TargetSchema.Resolved() to check targetSchema column default expressions
A couple SchemaTarget implementations weren't checking if the targetSchema was resolved as part of the Resolved() method. Added tests, audited the other implementations, and simplified the logic to use a new method on Schema to check that column default expressions are resolved.
Fixes: #6206
Dolt CI Run: #6213
1846: update information_schema.processlist to correctly display status of processes and databases
We used to hardcode "Query", now we reference process.Command
Additionally, we now get the database from the current session and use that variable.
fix for: #6023
1843: Improvements to CAST and CONVERT functions
This PR adds support for casting/converting to FLOAT and DOUBLE types with the CAST and CONVERT functions. It also adds support for length (aka precision) and scale type constraints (e.g. CAST(1.2345 AS DECIMAL(3,2))).
Parser support for DOUBLE and FLOAT with CAST and CONVERT: dolthub/vitess#249
Fixes: #5835
