…iner review (OtterMind#1914) - new HiveIdentifierProcessor (SPI ISQLIdentifierProcessor): quoteIdentifier with backtick doubling, escapeString doubling backslashes then single quotes - HiveMetaData overrides getSQLIdentifierProcessor(); metadata call sites use it - builder/DBManager/enums use HiveIdentifierProcessor.INSTANCE - non-escapable validation moved to HiveSqlGuards (engine/charset/collation names, numeric defaults, index sort direction) - HiveSqlEscapes removed; tests migrated (18 green)

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.

New HiveSqlEscapes (backtick identifiers) across MetaData/DBManager/SqlBuilder/constants/type enums; keyword positions whitelist-validated.

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.
