…intainer review (OtterMind#1914) - SqliteIdentifierProcessor gains INSTANCE, escapeString (single-quote doubling) and static escapeIdentifier; quoteIdentifier overloads delegate - SqliteMetaData/DBManager use getSQLIdentifierProcessor()/INSTANCE - builders/enums use SqliteIdentifierProcessor.escapeIdentifier - non-escapable validation moved to SqliteSqlGuards (safe names, type names, column defaults, line comments) - SqliteSqlEscapes removed; tests migrated (16 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.
What changed (24 sites)
New SqliteSqlEscapes across DBManager/MetaData/Builder/type enums; comment line-break sanitization; identifier processor only quotes non-plain names (benign output byte-identical).

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.
