Most checks run automatically in CI, so the manual "run X locally" checklist
items were redundant. Add an "Automated checks" section listing what CI runs
(PHP syntax check, PHPStan, PHP-CS-Fixer, PHPUnit, the PSR-4 gates, composer
audit) and drop the local syntax-check / phpunit checklist items. Also remove
the stale Git LFS line (the repo commits binaries directly, not via LFS). Keep
the human-judgment items: conventions, tests for the change, docs, no secrets.
