* Implement a vault that holds underlying (AMPL) and perp (SPOT) tokens and auto-rebalances to maintain the system's target deviation ratio via IRolloverVault swaps.

Key features:
- Deposit underlying tokens and mint vault notes (LP tokens)
- Redeem notes for proportional underlying + perp tokens
- Auto-rebalance when system DR is outside equilibrium zone:
    DR < 1 (perpTVL too high): redeem perps to decrease perpTVL
    DR > 1 (perpTVL too low): mint perps to increase perpTVL
- Rebalance formula: requiredChange = perpTVL × |dr - targetDR|
  (rolloverVaultTVL unchanged during flash mint/redeem)
- Liquidity limits based on swap direction:
    underlying->perp: limited by underlying balance
    perp->underlying: limited by perp value held
- Separate lag factors and percentage limits for each direction
- Slippage protection with configurable max swap fee percentage
- Keeper-controlled pause functionality.

* Update DRBalancerVault deposit/redeem to accept both tokens with slippage protection

- Update deposit() to accept both underlying and perp tokens with signature:
  deposit(underlyingAmtMax, perpAmtMax, minNotesMinted)
- Update redeem() to include slippage protection with signature:
  redeem(notesAmt, minUnderlyingAmtOut, minPerpAmtOut)
- Update computeMintAmt() to return (notesMinted, underlyingAmtIn, perpAmtIn)
- First deposit accepts any ratio; subsequent deposits enforce vault ratio
- Update Deposited event to include perpAmtIn
- Fix lag factor comments (swapped DR conditions)
- Add InvalidLagFactor validation to prevent division by zero
- Update contract docstring to reflect dual-token deposits
