[php-src] Issue #24697: sapi/cli: PHP_HTTP_PARSER_STRICT is defined but never referenced, so STRICT_CHECK() is always a no-op

Issue: https://github.com/php/php-src/issues/24697 Author: akku1139 ### Description The strict-mode switch name differs between the header and the implementation, so all STRICT_CHECK() sites are compiled out. The header logic is also inverted: passing -DPHP_HTTP_PARSER_STRICT reduces the value to 0 instead of enabling strict mode. As a result, "strict mode" cannot be enabled by any build option. - Request line ending with bare LF -> 200 (expected: reject) - Header line ending with bare LF -> 200 (expected: reject) - Blank line ending with bare LF -> 200 (expected: reject) - HTTP/9.9 -> 200, and the response status line echoes "HTTP/9.9 200 OK" - HTXP/1.1, HXXP/1.1 (protocol name typo) -> 200 (expected: reject) - HTTP/1.1 without Host -> 200 (expected: 400) AI Attribution: found by GPT-6 Luna, tested by DeepSeek V4.1 Flash ### PHP Version ```plain PHP 8.7.0-dev (cli) (built: Oct 26 2026 01:58:06) (NTS) Copyright © The PHP Group and Contributors Zend Engine v4.7.0-dev, Copyright © Zend by Perforce with Zend OPcache v8.7.0-dev, Copyright ©, by Zend by Perforce ``` ### Operating System _No response_
