updateContextFromSql

protected void updateContextFromSql(String sql)

Update the connection's cached catalog/schema when USE DATABASE/SCHEMA is executed. Decided from LEXER TOKENS, not string offsets: the former prefix check ran on whitespace-NORMALIZED text while its substring offsets indexed the RAW text, so extra whitespace cut into the name — and a quoted name kept its quotes and was then case-folded. Only the exact single-statement shapes update the cache; USE SCHEMA db.sc updates both halves.
