Add comprehensive documentation for type-parameter-level nullability checks using JSpecify annotations in Vaadin Flow. Covers: - Overview of JSpecify and type parameter nullability pattern - Benefits of compile-time null safety - @NullMarked annotation for class and package levels - Static analysis with NullAway - Current usage in Signal APIs with examples - Working with nullable and non-null signals - Custom generic classes with nullable type parameters - List and collection type nullability - Best practices for null safety Based on PR vaadin/flow#23630 which introduced type-parameter-level nullability for Signal APIs. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

I wonder if need to document NullAway plugin and compiler config as the must-have option, see https://github.com/vaadin/signals-cases/blob/45334f4655a895dce48c4260a30af69af15557bf/pom.xml#L101 ? |
