fix: OptimizerV3Push3 as IOptimizer always returns bear defaults — integration risk (#1063)

Browse source 
- getLiquidityParams() now reverts with "OptimizerV3Push3: not for production use" instead
  of silently returning zeroed bear-mode defaults; LiquidityManager.recenter() already has
  a try/catch fallback so backtesting is unaffected
- Added @custom:experimental NatSpec annotation to the contract marking it as a transpiler
  harness / backtesting stub only
- DeployBase.sol now validates any pre-existing optimizer address by calling getLiquidityParams()
  and reverting if it fails, blocking accidental wiring of OptimizerV3Push3 as a live optimizer
