I've restarted maintainance on my PHP "memio" libs.
Just like what's been done already in ../model,
please make the following changes, each in their own separate atomic commit:

• chore: update LICENSE to 2026
• chore: setup git push hook to check v prefix on tags
• chore: dockerized for local development
  note: use PHP 8.0 for the image, make sure composer isn't used in the build
• chore: upgraded PHP CS fixer to v2.19.3
  note: make separate chore: fixed CS commit if necessary
• chore: installed rector as a dev depdendency
  note: make separate chore: fixed rector errors commit if necessary
• chore: installed swiss-knife as a dev depdendency
• chore: installed phpstan as a dev depdendency
  note: make separate chore: fixed phpstan errors commit if necessary
• chore: changed tooling from scripts to Makefile
• chore: setup Github Actions
• chore: updated documentation
  note: remove travis or SensioLabsInsight badges where necessary

Make sure to also update the .gitignore along the way, it needs to follow this format:

# composer
composer.lock
vendor/

# friendsofphp/php-cs-fixer
.php_cs.cache
.php-cs-fixer.php
.php-cs-fixer.cache

# phpstan
phpstan.neon

# phpunit
phpunit.xml
.phpunit.result.cache

When it's time to commit, follow this format:
