• 7421: Add support for @@dolt_transaction_commit_message

  Documentation updates: dolthub/docs#1996
• 7412: When aborting a merge/cherry-pick, avoid resetting ignored tables.
  Tables that match dolt_ignore in the working set should be ignored by most operations.
  (CAVEAT: If we want to match git, these tables should only be ignored if there are not staged/HEAD versions of those tables. But we appear to not match git in that regard right now.)
  This PR changes the logic for aborting merges to avoid modifying any tables match dolt_ignore
• 7410: Prevent panic when sorting by commit_hash in various dolt system tables
  The analyzer rule replacePkSort does not work over certain types of indexes as some indexes are unordered.
  Certain dolt system tables use a MockIndex because they are not backed by a datastore.
  Unfortunately, we don't have a proper nil check for the idxSch, leading to a panic when attempting to sort by columns in those mock indexes
  This PR adds a nil check, so we don't try to use these indexes.
  fixes #7404
• 7408: Adds support for dolt log --stat
  Adds support for dolt log --stat which prints the diffstat for each commit in the log.
• 7401: fix bats tests to include backticks for column names in default and generated expressions
  companion pr: dolthub/go-mysql-server#2291
  fixes #7388
• 7390: Concurrent table deletion and schema modification should be reported as a schema conflict.
  Previously during a merge, if one branch altered a table schema and the other branch deleted the table, this would be an error that would automatically abort the merge. Now it's a schema conflict.

• 2295: allow tables with self referential foreign keys to be dropped
  Our logic for preventing DROPs on a table if that table was referenced in a FOREIGN KEY did not account for when the table was self referencing. This PR fixes that and closes the gap in our testing for this area.
  fixes #7418
• 2294: match range key with range type
  Creating lookups when comparing columns of different types were causing problems.
  Especially, if one of the types is a string.
  This is not a perfect fix as we don't do truncation yet, but it will stop panics.
  Reused solution from this PR:
  dolthub/go-mysql-server#2177
  It fixes the test case in this issue, but a skipped test is added for missing truncation functionality.
  #7371
• 2291: backquote column names in default and generated column expressions
  To prevent parsing errors for special column names, we need to wrap column identifiers with backquotes.
  MySQL prints column identifiers in default and generated expressions when doing show create table ... with backquotes anyways.
  fixes #7388
• 2288: Add more join statistic tests, some bug fixes
• 2285: Avoid generating SemiJoins when the subquery contains an OFFSET expression, as doing say may generate incorrect results.

Closed Issues
