Pull request overview

This pull request introduces a new SignedExclusiveSwap extension for the Ekubo protocol. The extension enables forward-only swaps with controller-signed, per-swap fee customization. It implements MEVCapture-style fee timing where fees are collected into extension storage and donated to LPs at the start of the next block, preventing same-block liquidity changes from capturing historical fees.

Changes:

• Adds SignedExclusiveSwap extension with EIP-712 signature verification for swap authorization
• Implements packed type definitions for gas-efficient storage of swap metadata and pool state
• Provides library helpers for off-chain signature computation and on-chain swap execution
• Includes comprehensive test coverage for the extension, though missing some edge case tests
