Pull request overview
This PR fixes issue #197 where extension types installed in the public schema (e.g., citext) failed to resolve when applying SQL to temporary schemas because the search_path only included the temp schema.
Key changes:
- Modified search_path in all schema application code to include both the target schema and public as a fallback
- Added
ParseSQLToIRWithSetup()function to execute setup SQL after schema recreation but before main SQL - Updated test infrastructure to make setup.sql files idempotent and demonstrate the fix with citext extension

| testdata/diff/create_table/add_column_cross_schema_custom_type/new.sql | Updated test to use unqualified citext type in public schema demonstrating natural usage pattern |
| testdata/diff/create_table/add_column_cross_schema_custom_type/plan.txt | Updated expected output to reflect citext being unqualified in public schema |

When applying SQL to temporary schemas, extension types installed in the public schema (e.g., citext) failed to resolve because the search_path only included the temp schema. Changes: - Add public to search_path in embedded.go, external.go, and testutil - Add ParseSQLToIRWithSetup() for tests needing setup SQL after schema reset - Fix type comparison to normalize schema prefix before comparing - Fix ADD COLUMN and ALTER COLUMN TYPE to properly unqualify types - Update test case to reproduce the bug with citext in public schema - Make setup.sql files idempotent for repeated execution 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
