v0.9.0-alpha

Implemented consistent event behavior:

• play_anim() emits frame 0 events and events from every crossed frame.
• { emit_events = false } disables events for the entire playback session.
• set_frame() and set_time() emit only destination-frame events.
• Their { emit_events = false } option affects only that operation.
• Seeking never emits events from intermediate frames.
• Existing queued events are preserved by play and seek operations.
• Event queues are bounded per component/handle; the default limit is 256.
• On overflow, the oldest events are dropped and a warning is logged once.
• Configure the limit with [spriteloop] max_pending_events in game.project.
• Queue statistics are available through get_info().
