Dependencies: php-parser token map for PHP 8.2+ host runs

[PurHur]

Problem

Running bin/vm.php / bin/jit.php on the host PHP 8.2 fails before compilation:

Fatal error: Undefined constant "T_OPEN_TAG_WITH_ECHO" in vendor/nikic/php-parser/.../Lexer.php

script/ci-local.sh passes PHPUnit because the test harness may use a different code path, but interactive DevEx on modern PHP is broken without Docker.

Goal

Developers can run examples and the compiler CLI on PHP 8.1–8.3 without a custom Docker image.

Scope

• Bump nikic/php-parser (and if needed ircmaxell/php-cfg) to versions whose token maps include PHP 8.x tokens
• Run composer update with locked versions; document minimum PHP in README (Docs: Rewrite README feature list to match current compiler (2026) #48)
• Smoke: php bin/vm.php -r 'echo 1;', php bin/vm.php -q name=World examples/001-SimpleWeb/example.php
• Ensure script/ci-local.sh still green

Acceptance criteria

• No fatal lexer errors on PHP 8.2 with project vendor/
• README states supported host PHP range
