Boop Engine Update: Clearer AI Animation Tool Feedback

AI animation workflows now return clearer tool feedback so the agent can reason about what changed without guessing.

• Animation player actions now return richer state readback after play, pause, stop, seek, autoplay, and root-motion updates.
• Animation graph edits now report applied values, skipped read-only parameters, and current values where relevant.
• Blend tree and state machine operations now return structured confirmation details for connections and transitions.
• Common animation failures now include stronger messages and hints for faster recovery, including parameter and index guidance.
