r4bbit d378628a80 refactor(amm): extract swap-output formula into amm_core ...

Lift the constant-product SwapExactInput math out of the guest's swap_logic
into amm_core::swap_exact_in_amounts(amount_in, reserve_in, reserve_out,
fee_bps) -> (effective_in, amount_out). swap_logic now calls it and keeps its
nonzero input/output asserts. Behavior-preserving (the two panic-message
tests still pass); the only change is that the impossible-overflow expects
become saturating.

Makes the on-chain pricing one reusable function so the off-chain swap quote
can produce byte-identical expected-output figures instead of re-deriving the
formula.
