- Add BacktestKraiken.sol: extends MockToken with Kraiken-compatible interface
(dual mint overloads — public mint(address,uint256) for EventReplayer and
restricted mint(uint256) for LiquidityManager; peripheryContracts() stubs
staking pool as address(0))
- Add KrAIkenDeployer.sol: library deploying OptimizerV3Push3 + LiquidityManager
on the shadow pool, wiring BacktestKraiken permissions, setting fee destination,
and funding LM with configurable initial mock-WETH capital (default 10 ETH)
- Add StrategyExecutor.sol: time-based recenter trigger (configurable block
interval, default 100 blocks); logs block, pre/post positions (Floor/Anchor/
Discovery tick ranges + liquidity), fees collected, and revert reason on skip;
negligible-impact assumption documented as TODO(#319)
- Modify EventReplayer.sol: add overloaded replay() accepting an optional
StrategyExecutor hook; maybeRecenter() called after each block advancement
without halting replay on failure
- Modify BacktestRunner.s.sol: replace tokenA/B with MockWETH + BacktestKraiken,
integrate KrAIkenDeployer + StrategyExecutor into broadcast block; configurable
via RECENTER_INTERVAL and INITIAL_CAPITAL_WETH env vars; executor.logSummary()
printed after replay

- Guard final drift sample with `idx % LOG_INTERVAL != 0` to prevent
double-counting stats when totalReplayed is an exact multiple of
LOG_INTERVAL (the loop's _logCheckpoint already fired for that state)
- Hoist pool.slot0() before the guard and pass finalSqrtPrice/finalTick
to _logSummary(), eliminating the redundant slot0 read inside it

- Cache pool.tickSpacing() as immutable in EventReplayer constructor
to avoid a repeated external call per _replayMint() invocation
- Rename driftCount → driftCheckpoints for consistency with log label
- Add sqrtDriftBps to the per-checkpoint progress log line, using the
now-live lastExpectedSqrtPrice field (previously written but never read)
- Guard _replaySwap(): skip and count events where amountSpecified ≤ 0,
which would silently flip exact-input into exact-output mode
- Add a final drift sample after the while-loop for trailing events not
covered by the last LOG_INTERVAL checkpoint
- Move EventReplayer construction outside the broadcast block in
BacktestRunner (it uses vm.* cheat codes incompatible with real RPC)
- Change second vm.closeFile() from try/catch to a direct call so errors
surface rather than being silently swallowed
