Collect dependencies defined in property hooks

[fain182]

Add support for collecting dependencies from PHP 8.4 property hooks:

• Handle typed parameters in set hooks (e.g., set(MyClass $value))
• Dependencies from expressions within hook bodies (new, static calls, etc.) are already collected by the AST traverser

Fixes #515

@fain182 I suggest adding few lines in the documentation too.

[fain182]

I don't think we need to add anything to the README for this. We don't document individual PHP language features that we support - the README doesn't have a section listing things like 'we support attributes' or 'we support enums' or 'we support readonly classes'. The expectation is that we support all PHP syntax.
