feat: add deleteBy, batched auto-save, source roundtrip - #1

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires ezimuel/phpvector ^0.3.0 -> satisfiable by ezimuel/phpvector[0.3.0]. - ezimuel/phpvector 0.3.0 requires php ^8.2 -> your php version (8.1.34) does not satisfy that requirement.
