Introduce the add-liquidity vertical mirroring the swap + createPool patterns,
for depositing into an existing pool via the AddLiquidity instruction.
FFI (amm_ffi):
- add_liquidity_quote — decode poolData, orient the caller's max amounts to the
pool's canonical order, run the guest's exact ideal->actual->delta_lp math, and
return { amountARaw, amountBRaw, expectedLpRaw, priceRaw } in display order.
Slippage-free like create's quote; the min-LP floor is applied at submit.
- add_liquidity_plan — canonicalize (token, max-amount, holding) as one unit,
take vaults + LP definition from poolData, emit the 10-account AddLiquidity
order (only the user holdings a/b/LP sign). Takes minLpRaw directly, like
swap_exact_in_plan takes min_out.
Shared with createPool: extract canonical_triples (the pair/amount/holding
canonical swap) and plan_response (the tx-submission envelope); both the create
and add plans now use them.
