Fixed Phalcon\Mvc\Model\Query (PHQL) parsing of identifiers whose name begins with the NOT keyword. Columns, tables, and aliases such as notice_id were truncated to ice_id (the leading not was dropped), causing the database to report the column as unknown - most visibly in Phalcon\Mvc\Model\Query\Builder join conditions built via createBuilder(). The scanner's re2c backtracking marker shared the token-start pointer, so the NOT BETWEEN rule advanced it past not; escaped identifiers containing internal escapes (e.g. [col\[0\]]) were corrupted by the same root cause.

Thanks
