Adds test/cost.test.ts covering the four exports of src/cost.ts:

  • JEV_USD_PER_MTOK: matches the published rate
  • newMeter: starts at zero
  • addJevCost: correct token→USD math, accumulation, edge cases (NaN, Infinity, negative, zero, non-numbers, numeric strings), undefined meter safety
  • addUsd: exact addition, accumulation, same edge cases

12 tests, all pass under bun test.
