IBX-12648: [Composer] Added conflict with twig/twig 3.29+ incompatible with Symfony 5.4

[alongosz]

🎫 Issue	IBX-12648

Description:

twig/twig 3.29.0 changed Twig\TemplateWrapper::unwrap() to require a Twig\Environment argument. symfony/twig-bundle 5.4.45 calls it without one, so cache warm-up fatals on every 4.6 instance:

PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function Twig\TemplateWrapper::unwrap(),
0 passed in vendor/symfony/twig-bundle/CacheWarmer/TemplateCacheWarmer.php on line 56 and exactly 1 expected
in vendor/twig/twig/src/TemplateWrapper.php:110

All 4.6 browser tests in the org went red the same day - 21 failing jobs across admin-ui, page-builder, form-builder, fieldtype-richtext, segmentation and commerce.

Symfony capped twig to <3.29.0 on their 5.4 branch (symfony/symfony@003d08c8c82f, symfony/symfony@7ec3eb09ec5e), but hasn't released it - the cap landed on 2026-09-14, and the latest 5.4 release is v5.4.53 from 2026-05-27. This mirrors it until a 5.4 release carrying it ships.

• [Composer] Added twig/twig: >=3.29 to conflict

Important

4.6 only. 6.4 and 7.4 avoid the call via Twig\BlockChain (symfony/symfony#66043), so this hunk must be dropped on merge-up to 5.0.

There's a second call site we don't hit yet only because cache warm-up dies first: TwigRendererEngine::loadResourcesFromTheme(), used when rendering form themes.

For QA:

No QA required. With the conflict in place composer resolves twig/twig to 3.28.0 and leaves symfony/twig-bundle at v5.4.45.

Documentation:

No documentation required.
