commit 70c71565c684fa96e222179271ecb13a156d80ad
    Fix UI object segfault by switching from managed to manual weakref management

    The UI types (Frame, Caption, Sprite, Grid, Entity) were using
    Py_TPFLAGS_MANAGED_WEAKREF while also trying to manually create weakrefs
    for the PythonObjectCache. This is fundamentally incompatible - when
    Python manages weakrefs internally, PyWeakref_NewRef() cannot access the
    weakref list properly, causing segfaults.

    Changed all UI types to use manual weakref management (like PyTimer):
    - Restored weakreflist field in all UI type structures
    - Removed Py_TPFLAGS_MANAGED_WEAKREF from all UI type flags
    - Added tp_weaklistoffset for all UI types in module initialization
    - Initialize weakreflist=NULL in tp_new and init methods
    - Call PyObject_ClearWeakRefs() in dealloc functions

    This allows the PythonObjectCache to continue working correctly,
    maintaining Python object identity for C++ objects across the boundary.

    Fixes segfault when creating UI objects (e.g., Caption, Grid) that was
    preventing tutorial scripts from running.

This is the bulk of the required behavior for Issue #126.
that issure isn't ready for closure yet; several other sub-issues left.
    closes #110
    mention issue #109 - resolves some __init__ related nuisances

commit 3dce3ec539ae99e32d869007bf3f49d03e4e2f89
    Refactor timer system for cleaner architecture and enhanced functionality

    Major improvements to the timer system:
    - Unified all timer logic in the Timer class (C++)
    - Removed PyTimerCallable subclass, now using PyCallable directly
    - Timer objects are now passed to callbacks as first argument
    - Added 'once' parameter for one-shot timers that auto-stop
    - Implemented proper PythonObjectCache integration with weakref support

    API enhancements:
    - New callback signature: callback(timer, runtime) instead of just (runtime)
    - Timer objects expose: name, interval, remaining, paused, active, once properties
    - Methods: pause(), resume(), cancel(), restart()
    - Comprehensive documentation with examples
    - Enhanced repr showing timer state (active/paused/once/remaining time)

    This cleanup follows the UIEntity/PyUIEntity pattern and makes the timer
    system more Pythonic while maintaining backward compatibility through
    the legacy setTimer/delTimer API.

    closes #121

commit 145834cfc31b8dabc4cb3591b9cb4ed99fc8b964
    Implement Python object cache to preserve derived types in collections

    Add a global cache system that maintains weak references to Python objects,
    ensuring that derived Python classes maintain their identity when stored in
    and retrieved from C++ collections.

    Key changes:
    - Add PythonObjectCache singleton with serial number system
    - Each cacheable object (UIDrawable, UIEntity, Timer, Animation) gets unique ID
    - Cache stores weak references to prevent circular reference memory leaks
    - Update all UI type definitions to support weak references (Py_TPFLAGS_MANAGED_WEAKREF)
    - Enable subclassing for all UI types (Py_TPFLAGS_BASETYPE)
    - Collections check cache before creating new Python wrappers
    - Register objects in cache during __init__ methods
    - Clean up cache entries in C++ destructors

    This ensures that Python code like:
    ```python
    class MyFrame(mcrfpy.Frame):
        def __init__(self):
            super().__init__()
            self.custom_data = "preserved"

    frame = MyFrame()
    scene.ui.append(frame)
    retrieved = scene.ui[0]  # Same MyFrame instance with custom_data intact
    ```

    Works correctly, with retrieved maintaining the derived type and custom attributes.

    Closes #112

commit c5e7e8e298
    Update test demos for new Python API and entity system

    - Update all text input demos to use new Entity constructor signature
    - Fix pathfinding showcase to work with new entity position handling
    - Remove entity_waypoints tracking in favor of simplified movement
    - Delete obsolete exhaustive_api_demo.py (superseded by newer demos)
    - Adjust entity creation calls to match Entity((x, y), texture, sprite_index) pattern

commit 6d29652ae7
    Update animation demo suite with crash fixes and improvements

    - Add warnings about AnimationManager segfault bug in sizzle_reel_final.py
    - Create sizzle_reel_final_fixed.py that works around the crash by hiding objects instead of removing them
    - Increase font sizes for better visibility in demos
    - Extend demo durations for better showcase of animations
    - Remove debug prints from animation_sizzle_reel_working.py
    - Minor cleanup and improvements to all animation demos

commit a010e5fa96
    Update game scripts for new Python API

    - Convert entity position access from tuple to x/y properties
    - Update caption size property to font_size
    - Fix grid boundary checks to use grid_size instead of exceptions
    - Clean up demo timer on menu exit to prevent callbacks

    These changes adapt the game scripts to work with the new standardized
    Python API constructors and property names.

commit 9c8d6c4591
    Fix click event z-order handling in PyScene

    Changed click detection to properly respect z-index by:
    - Sorting ui_elements in-place when needed (same as render order)
    - Using reverse iterators to check highest z-index elements first
    - This ensures top-most elements receive clicks before lower ones

commit 6813fb5129
    Standardize Python API constructors and remove PyArgHelpers

    - Remove PyArgHelpers.h and all macro-based argument parsing
    - Convert all UI class constructors to use PyArg_ParseTupleAndKeywords
    - Standardize constructor signatures across UICaption, UIEntity, UIFrame, UIGrid, and UISprite
    - Replace PYARGHELPER_SINGLE/MULTI macros with explicit argument parsing
    - Improve error messages and argument validation
    - Maintain backward compatibility with existing Python code

    This change improves code maintainability and consistency across the Python API.

commit 6f67fbb51e
    Fix animation callback crashes from iterator invalidation (#119)

    Resolved segfaults caused by creating new animations from within
    animation callbacks. The issue was iterator invalidation in
    AnimationManager::update() when callbacks modified the active
    animations vector.

    Changes:
    - Add deferred animation queue to AnimationManager
    - New animations created during update are queued and added after
    - Set isUpdating flag to track when in update loop
    - Properly handle Animation destructor during callback execution
    - Add clearCallback() method for safe cleanup scenarios

    This fixes the "free(): invalid pointer" and "malloc(): unaligned
    fastbin chunk detected" errors that occurred with rapid animation
    creation in callbacks.

commit eb88c7b3aa
    Add animation completion callbacks (#119)

    Implement callbacks that fire when animations complete, enabling direct
    causality between animation end and game state changes. This eliminates
    race conditions from parallel timer workarounds.

    - Add optional callback parameter to Animation constructor
    - Callbacks execute synchronously when animation completes
    - Proper Python reference counting with GIL safety
    - Callbacks receive (anim, target) parameters (currently None)
    - Exception handling prevents crashes from Python errors

    Example usage:
    ```python
    def on_complete(anim, target):
        player_moving = False

    anim = mcrfpy.Animation("x", 300.0, 1.0, "easeOut", callback=on_complete)
    anim.start(player)
    ```

    closes #119

commit 9fb428dd01

    Also updated existing references:
    - #101/#110: Constructor standardization
    - #109: Vector class indexing

    Note: Tutorial-specific items and Python-implementable features
    (input queue, collision reservation) are not tracked as engine issues.

commit 062e4dadc4
    Fix animation segfaults with RAII weak_ptr implementation

    Resolved two critical segmentation faults in AnimationManager:
    1. Race condition when creating multiple animations in timer callbacks
    2. Exit crash when animations outlive their target objects

    Changes:
    - Replace raw pointers with std::weak_ptr for automatic target invalidation
    - Add Animation::complete() to jump animations to final value
    - Add Animation::hasValidTarget() to check if target still exists
    - Update AnimationManager to auto-remove invalid animations
    - Add AnimationManager::clear() call to GameEngine::cleanup()
    - Update Python bindings to pass shared_ptr instead of raw pointers

    This ensures animations can never reference destroyed objects, following
    proper RAII principles. Tested with sizzle_reel_final.py and stress
    tests creating/destroying hundreds of animated objects.
