stock-vs-industry using NQUSB benchmark idexes

Original idea from Stock versus Industry by Tr33man.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
═══ PRIMARY IMPROVEMENT: NQUSB Hierarchical Index Benchmarks ═══
The KEY improvement: Multi-Level Industry Granularity with Drill-Down/Drill-Up Navigation
From: Simple ETF Comparison (1 Level) Stock → Industry ETF (e.g., "SOXX" for all semiconductors)
To: NQUSB Hierarchical Comparison (4 Levels)

• Level 4 (Primary): NQUSB10102010 → Semiconductors (most specific)
  
• Level 3 (Secondary): NQUSB101020 → Technology Hardware and Equipment
  
• Level 2 (Tertiary): NQUSB101010 → Software and Computer Services
  
• Level 1 (Quaternary): NQUSB10 → Technology (broadest sector)
  

Users can now drill up and down the industry hierarchy to see how their stock performs against different levels of industry classification!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
═══ WHY THIS MATTERS ═══

Original Limitations:

• Single comparison level - ETF only
  
• No drill-down capability - Can't zoom in to more specific industries
  
• No drill-up capability - Can't zoom out to broader sectors
  
• ETF limitations - Not all industries have dedicated ETFs
  
• Arbitrary mappings - Manual ETF selection may not represent true industry
  

Improved Capabilities:

• 4-level hierarchical navigation - Drill-down and drill-up through industry classifications
  
• 361 NQUSB official indices - NASDAQ US Benchmark Index structure
  
• Official NASDAQ classification - Industry-standard taxonomy
  
• Large Mid Cap (LM) option - Focus on larger companies when needed
  
• Enhanced UI - Clear level indicators and full index descriptions
  

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
═══ EXAMPLE: ANALYZING NVDA (Semiconductors) ═══

Level 4 - Primary (Most Specific):
NQUSB10102010 - Semiconductors
→ NVDA vs. AMD, AVGO, QCOM, TXN, etc. (direct competitors)

Level 3 - Secondary (Broader):
NQUSB101020 - Tech Hardware & Equipment
→ NVDA vs. AAPL, CSCO + semiconductors

Level 2 - Tertiary (Even Broader):
NQUSB101010 - Software and Computer Services
→ NVDA vs. all tech hardware

Level 1 - Quaternary (Broadest):
NQUSB10 - Technology Sector
→ NVDA vs. entire technology sector

You can now zoom in to see direct competitors or zoom out to understand macro sector trends - all in one indicator!
