Supernova AMO

What was done

• Refactored the Sonic SwapXAMO strategy into a generalized Algebra-based strategy.
• Updated strategy behavior to accept pool tokens in any order, removing token-order assumptions.
• Kept strategy behavior consistent while improving flexibility and reuse across Algebra-style pools.

Test fixes and updates

• Fixed existing Sonic fork tests that were broken or outdated after the refactor.
• Adjusted fork test setup and assertions to match the new generalized strategy interface/flow.
• Updated test cases to validate compatibility with the refactored format and token-order handling.

Why this change

• The prior SwapXAMO implementation was too specialized and was expecting ws / OS tokens in specific order. Also the strategy was named SwapX even though the pool engine underneath was Algebra
• Ensuring token-order-agnostic handling prevents integration issues across pools with varying token ordering.

What isn't done

• The strategy still expects both tokens to have 18 decimal format. Additional work is required to make strategy support non 18 decimal tokens.

Code review suggestions

• The swapXAMO is refactored to a new location. A diff tool should be used diffing the new StableSwapAMMStrategy with the old SonicSwapXAMOStrategy
