v0.2.0 - PSR-4 Refactor

Breaking Changes

• SharedStore replaces stdClass — All run(), prep(), post() now expect PocketFlow\SharedStore instead of stdClass
• Async methods renamed to camelCase — run_async() → runAsync(), prep_async() → prepAsync(), etc.
• Namespaces — All classes now in PocketFlow\ namespace. Add use PocketFlow\Node; etc.
• PSR-4 structure — 14 files instead of the old single PocketFlow.php

Added

• SharedStore class with #[AllowDynamicProperties] for PHP 8.2+
• AsyncRunnable interface for mixing sync/async nodes in flows
• AsyncLogicTrait for reusable async retry logic
• Agent Skills package (.agents/skills/pocketflow-php/) for AI coding tools
• New tests for edge cases

Changed

• $maxRetries and $wait are now readonly constructor properties
• Exceptions instead of trigger_error() calls
• Improved PHPDoc documentation on all methods
