[Feature] Multi-Hop Swap Routing Logic

[AlAfiz]

Description: Implement a Router contract capable of chaining multiple swaps together in a single transaction (e.g., swapping Token A -> Token B -> Token C).
Context / Motivation: Users shouldn't need to perform multiple manual transactions if a direct pair (A to C) doesn't exist or lacks liquidity. The Router is essential for seamless UX.
Acceptance Criteria: - [ ] Create a swap_exact_tokens_for_tokens function that takes a Vec<Address> representing the path.

• Iterate through the path, executing swaps sequentially on the respective pool contracts.
• Verify the final output amount matches or exceeds the user's amount_out_min slippage parameter.
• Revert the entire transaction if the slippage tolerance is breached.
  Technical Pointers: The router shouldn't hold funds; it should act as an intermediary. Rely heavily on env.authorize_as_client() to allow the router to pull the initial token from the user, then handle subsequent cross-contract calls.
