feat(Agente 1): Implement FX Creator MCP Tools (T031-T035)

Browse Source 
- Add 5 new MCP tools to server.py:
  * create_riser (T031) - Pre-drop buildup effect
  * create_downlifter (T032) - Post-drop energy release
  * create_impact (T033) - Hit, crash, sub_drop, noise impacts
  * create_silence (T034) - Break/silence effects
  * create_fx_section (T035) - Complete FX sections

- Add 5 handlers to __init__.py for Remote Script execution
- Update skill_produccion_audio.md with FX tools documentation

All tools exposed and ready for professional FX generation.
