Pull request overview

Updates the tiny-blocks Collection library to better support closure-based factories that return arrays, while tightening up predicate compilation behavior and normalizing project metadata/tooling.

Changes:

• Allow EagerPipeline::fromClosure() to accept either an array or a Traversable result from the factory.
• Make Filter predicate compilation explicitly drop only null predicates.
• Normalize/refresh project metadata and contributor tooling/docs (Composer normalization, README overview, editor config, Claude rules).
