3dtours 3f7abe0c95 feat: AI Rearrange Scenario Detection from spec 45_SCENARIAO_AI
- 9 rearrange scenarios with keyword matching (arpeggio, harmonies,
  syncopation, walking bass, jazz, synthwave, cinematic, simplify, chromatic)
- detectRearrangeScenario() maps user prompt to specific technique rules
- buildRearrangeMessage auto-injects scenario-specific technique guidance
- 9 rearrange presets added to PromptTemplateManager (Rearrange / Variation)

This is critical to avoid output token limit timeouts. The required structure to return via the `generate_multitrack_midi` tool consists of 3 tracks: 1. Strings: plays smooth legato chord changes (one chord per 1 or 2 bars). 2. Brass Theme: plays a swelling simple melodic line in the C3-C5 range. 3. Epic Percussion: hits heavily on beats 1 and 3. Ensure the duration is precisely 8 bars (32 beats).",
