CHANGE COLUMN is MySQL-specific syntax that Snowflake does not support. Use RENAME COLUMN "old" TO "new" (valid Snowflake, with quoted identifiers for mixed-case names). Fixes OtterMind#2183 Co-Authored-By: Claude <noreply@anthropic.com>

…ENAME Replaces direct " concatenation with SnowflakeMetaData.SNOWFLAKE_SQL_IDENTIFIER_PROCESSOR.quoteIdentifierAlways for DROP COLUMN, CREATE TABLE schema qualifier, and RENAME COLUMN. CHANGE COLUMN (MySQL syntax) is replaced with RENAME COLUMN (Snowflake). Built on the SPI extension (OtterMind#2234). Closes OtterMind#2169, OtterMind#2185, OtterMind#2186 (superseded by this SPI-based approach) Co-Authored-By: Claude <noreply@anthropic.com>
