… per maintainer review (OtterMind#1914) - strengthen KingBaseSQLIdentifierProcessor (SPI ISQLIdentifierProcessor): quoteIdentifier always double-quotes with embedded-quote doubling, escapeString doubles single quotes; INSTANCE for call sites without MetaData access - KingBaseMetaData returns the processor from getSQLIdentifierProcessor(); metadata call sites use it (KINGBASE_SQL_IDENTIFIER_PROCESSOR removed) - DBManager/builder/enums use KingBaseSQLIdentifierProcessor.INSTANCE - non-escapable validation moved to KingBaseSqlGuards (safe expressions, index methods) - KingBaseSqlEscapes removed; tests migrated (15 green)
…uote for DDL paths (OtterMind#1914)

Part of the SQL-injection hardening tracked in #1914. Prior art: #2052 (Oracle), #2053 (SQL Server), and the wave-1 batch (#2172-#2177).
These are second-order injection paths: values such as table/schema/view/index names originate from the connected database's own metadata, so exploitation requires a maliciously named object in a target database.
What changed (59 sites)
New KingBaseSqlEscapes applied across MetaData/DBManager(search_path)/SqlBuilder/type enums; index access methods whitelist-validated; identifier processor quote-doubling.

This branch also passed a two-lens adversarial review (escape-correctness/coverage + regression/test-efficacy); all blocking findings were fixed and re-tested before submission.
