This is surfacing a bunch of false positives that we need to resolve first, aka merging after 0.9.0 |

Can you post some examples of these false positives? |

Add two new diagnostic collectors to the type mismatch family: - type_mismatch_return: checks return statements against declared return types. Flags incompatible types, void functions returning values, and bare return; in non-void functions. Skips generators, abstract methods, mixed/untyped returns. - type_mismatch_property: checks $this->prop and self::$prop assignments against declared property types. Only plain = assignments; compound operators are skipped. Both reuse the existing is_type_compatible() policy layer and resolve_expression_type() infrastructure. A unified collect_type_mismatch_diagnostics() entry point groups all three collectors (argument, return, property). Closes #201
