10357: Prevent temporary table name collisions

fixes #10353

MySQL allows creating temporary tables with the same names as existing non-temporary tables and creating non-temporary tables with the same names as existing temporary tables. However, temporary tables cannot have the same name as other temporary tables.

Our previous implementation seemed to have assumed temporary tables with the same names were allowed. Each session had a map of db names to an array of tables, and new temporary tables were added to the end of the array, without checking if there was a table with an existing name. When fetching or dropping a temporary table, we iterated through the array and returned/dropped the first table with a matching name; this meant even though we allowed temporary tables with the same name, we only ever operated on whichever one was created first.

Since temporary tables with the same names are actually not allowed, the array of temporary tables was replaced with a name-to-table map to make fetching a temporary table with GetTemporaryTable faster. This also makes DropTemporaryTable faster. This does make GetAllTemporaryTables slower since we now have to iterate over the mappings to create an array for temporary tables, but GetAllTemporaryTables doesn't seem to be called as frequently as GetTemporaryTable.
10349: Remove requirement for -i in dolt_rebase

Hold over from the original impl of rebase now addressed!
10274: dolt stash apply

Adds #10131

Adds dolt stash apply. Functions similar to drop and pop in usage: accepts no argument for most recent stash, or int or stash@{int} for non-top stashes. i.e. dolt stash apply 2 or dolt stash apply stash@{2}.
10227: dolthub/dolt#5862: Add ignore system table
Summary
Adds a new dolt_status_ignored system table that extends dolt_status functionality by including an ignored column to identify which unstaged tables match patterns defined in dolt_ignore. This provides a SQL interface equivalent to dolt status --ignored.
Changes
New System Table
dolt_status_ignored - Same schema as dolt_status plus an ignored column:

table_name (text): Name of the table
staged (boolean): Whether the table is staged
status (text): Status of the table (e.g., "new table", "modified", "conflict")
ignored (boolean): Whether the table matches a dolt_ignore pattern

Implementation Details
The implementation started with logic similar to status_table.go and was then refactored to share common code between both tables while adding the ignore-checking functionality.

go/libraries/doltcore/doltdb/system_table.go

Added StatusIgnoredTableName constant
Registered table in GeneratedSystemTableNames() and DoltGeneratedTableNames

go/libraries/doltcore/sqle/database.go
Added switch case for StatusIgnoredTableName in getTableInsensitiveWithRoot()
Extracted getStatusTableRootsProvider() helper to eliminate duplicate logic between dolt_status and dolt_status_ignored switch cases

go/libraries/doltcore/sqle/dtables/status_table.go
Added getStatusRowsData() function using existing statusTableRow struct to share status collection logic between both tables
Refactored newStatusItr() to use shared function

go/libraries/doltcore/sqle/dtables/status_ignored_table.go (new file)
Implements StatusIgnoredTable and StatusIgnoredItr
Uses shared getStatusRowsData() from status_table.go
Uses adapter pattern via DoltTableAdapterRegistry similar to StatusTable
Adds ignore-checking logic via helper functions:
getIgnorePatterns(): Fetches patterns from dolt_ignore
buildUnstagedTableNameSet(): Creates set for quick lookup
checkIfIgnored(): Checks if table matches ignore pattern (returns error on failure)

Behavior

Unstaged tables: ignored=1 if table name matches a pattern in dolt_ignore, ignored=0 otherwise
Staged tables: Always ignored=0 (staging overrides ignore patterns, matching git behavior)
Constraint violations, merge conflicts, schema conflicts: Always ignored=0

Tests
BATS integration tests
integration-tests/bats/system-tables.bats:

Basic functionality: Verifies ignored column correctly identifies ignored tables while non-ignored tables have ignored=0
Staged tables: Confirms staged tables always have ignored=0 regardless of ignore patterns
System table visibility: Ensures table appears in dolt ls --system

integration-tests/bats/ls.bats:
Updated "ls: --system shows system tables" to include dolt_status_ignored (27 tables instead of 26)

Go enginetests
go/libraries/doltcore/sqle/enginetest/dolt_queries.go:

Closes #5862

3395: fewer strings.ToLower calls in gatherTableAlias

3393: add transform.InspectWithOpaque function

This changes transform.Inspect to not apply the helper function on children of sql.OpaqueNodes.

Additionally, it adds a transform.InspectWithOpaque that does.

This is to match transform.Node and transform.NodeWithOpaque.

There are still some inconsistencies between the different transform helper functions:

transform.Node:


post order (applies to node.Children then node)
no way to break out early


transform.Inspect:


pre order (applies to node then node.Children)
can break out early (only on all or none of children)
return true to continue


transform.InspectExpr:


post order (applies to expr.Children then expr)
can break out early, including stopping during children
return false to continue


3389: remove convertLeftAndRight

This PR removes c.convertLeftAndRight, which avoids calls to c.Left().Type() and c.Right().Type().

Not entirely sure why receiver methods would impact performance this much, but benchmarks say so.
