Redesign integration test matrix without --prefer-lowest

[JanTvrdik]

Summary

• Removes --prefer-lowest second test pass from run-integration.sh; instead, each matrix file explicitly tests the latest patch of one specific minor version using X.Y.* constraints
• Eliminates PHP version splits — each matrix file covers the full PHP range supported by that package version, with appropriate MIN/MAX bounds
• Removes unnecessary secondary COMPOSER_REQUIRE entries that were only needed for --prefer-lowest compatibility
• Adds --rm to docker-compose run in run-in-docker.sh to prevent orphan containers
• Fixes PHP 8.4 implicit nullable deprecation in MigrationsExtension.phpt

Matrix file changes

Group	Old files	New files	Versions covered
dbal/doctrine	6	25	2.5–4.4
dbal/nextras	6	8	1.0–5.0
dbal/dibi	4	8	3.0–5.1
dbal/nette	3	4	2.4–3.2
nette-di	6	4	2.4–3.2
symfony-bundle	8	18	4.4, 5.0–5.4, 6.0–6.4, 7.0–7.4, 8.0

Notable findings during testing

• Doctrine DBAL 2.12–2.13 and 3.0–3.2 fail on PHP 8.2+ due to ${var} string deprecation → capped at PHP 8.1
• Symfony 4.0–4.3 blocked by Composer 2.9.5 security advisory enforcement (EOL versions) → removed, only 4.4 LTS kept
• Symfony 6.0–6.2 need symfony/console pinned to same minor to prevent resolution to 7.x+ → capped at PHP 8.3 (implicit nullable in framework-bundle on 8.4)
• Symfony yaml must be pinned to same minor as framework-bundle to prevent cross-major resolution

Test plan

• All matrix files verified locally via tests/run-in-docker.sh on appropriate PHP versions
• Representative tests passing for each group (doctrine, nextras, dibi, nette, nette-di, symfony-bundle)

Pull request overview

This pull request redesigns the integration test matrix by removing the --prefer-lowest testing approach and replacing it with explicit version pinning using X.Y.* constraints. This simplification reduces the number of test runs per matrix file from 2 to 1, while consolidating PHP version ranges within each matrix file rather than splitting them across multiple files.

Changes:

• Removed --prefer-lowest logic from the integration test runner script
• Consolidated matrix files from 33 to 67 files (more granular version coverage, but simpler per-file structure)
• Updated all matrix files to use X.Y.* constraints for the primary package being tested and appropriate caret/wildcard constraints for dependencies
• Added --rm flag to docker-compose to prevent orphan containers
• Fixed PHP 8.4 implicit nullable deprecation in MigrationsExtension.phpt
