Agent Cost Crisis Benchmark - The Compelling Story

This benchmark demonstrates WHY Headroom matters by showing:

1. THE PROBLEM: Context explosion in real-world agent workloads
   - Tokens grow exponentially with conversation length
   - Tool outputs dominate context (often 70%+ of tokens)
   - Dynamic content breaks cache efficiency

2. THE SOLUTION: Headroom's impact on real workloads
   - Token reduction from SmartCrusher (50-80% on tool outputs)
   - Cache alignment improvement (10x+ potential savings)
   - Context windowing (stay within limits without losing info)

3. THE PROOF: Quality preservation
   - Critical information retained (errors, anomalies, relevant items)
   - Agent task completion unaffected
   - Information retrieval accuracy maintained
