New Tools: Arrangement Composition Analysis & Rack Macro Control

Added 6 new MCP tools: 5 arrangement composition analysis tools and 1 Rack macro setter.

Arrangement Composition Analysis (5 new compound tools — MCP_Server/tools/arrangement.py)

• get_arrangement_overview — full arrangement map: tempo, time sig, per-track clips, cue points, sections
• analyze_arrangement_density — divide arrangement into time regions, compute clip density per region
• analyze_arrangement_sections — detect song sections from cue points or clip density changes, characterize each section (sparse, building, peak, breakdown)
• analyze_note_content — aggregate note statistics: pitch range, velocity, key/scale detection (Krumhansl-Schmuckler), pitch class distribution
• compare_arrangement_sections — compare two time regions for structural similarity (track overlap, clip names, density)

Devices (1 new tool — MCP_Server/tools/devices.py)

• set_rack_macro — set Rack macro knob values by index (wraps Remote Script set_macro_value command)

Tool count: 340 core + 19 optional (ElevenLabs) = 359 total
