Instant Upgrades with Rector
summary
Codebase migration uses an AST with nikic/php-parser and a set of automated rules so refactors apply patternwise not filewise, cutting 44,000 lines (200,000 total) across 151 routes in about 80 hours of rule development. Rector claims it fixes roughly 80% of upgrade chores, provides rule sets for Symfony, Nette, Twig, Doctrine, PHPUnit, can add typehints to remove PHPStan errors, and runs in CI to apply and verify changes automatically.
