* Endless Mode Token Economics Calculator
*
* Simulates the recursive/cumulative token savings from Endless Mode by
* "playing the tape through" with real observation data from SQLite.
*
* Key Insight:
* - Discovery tokens are ALWAYS spent (creating observations)
* - But Endless Mode feeds compressed observations as context instead of full tool outputs
* - Savings compound recursively - each tool benefits from ALL previous compressions
