feat: regenerate cost models after rebase to account for validation overhead

Regenerate cost model parameters based on fresh benchmark runs after
rebasing on master. This accounts for the negative amount validation
added to valueContains in commit 531f1b8.

Updated cost models:
- lookupCoin: linear_in_z (intercept: 203599, slope: 7256)
- valueContains: linear_in_y (intercept: 1000, slope: 130720)
- valueData: constant_cost (156990)
- unValueData: linear_in_x (intercept: 1000, slope: 36194)

The benchmark data includes 350 measurement points across varying input
sizes. All three cost model variants (A, B, C) have been updated
consistently with identical parameters.
