Add table-driven Foundry tests for OptimizerV3.calculateParams covering:
- Bear regime at 0%, 1%, 50%, 91% staking (all tax rates)
- Bull/bear boundary at 92% with tax index transitions
- Bull/bear at 95% with penalty=50 exact boundary
- EffIdx shift behavior at 96% (taxIdx 13→14 discontinuity)
- Bull at 97% with max tax, 100% always bull
- Edge cases: all-zero inputs, zero tax at high staking
- Mantissa overflow guard
- Unused slots ignored
- Fuzz: no reverts, output always exactly bear or bull
