Bring pool creation onto the redesigned lean module surface
mirroring the shipped swap vertical.
FFI (amm_ffi):
- amm_liquidity_quote: a pure create-pool preview from the two deposit
amounts — expectedLpRaw / initialPriceRaw / lockedLpRaw via the shared
amm_core opening-LP math (isqrt_product, MINIMUM_LIQUIDITY,
spot_price_q64_64), so the preview equals what new_definition mints. No
chain reads, no quoteHash, and no fee input (the fee is neither part of the
pool PDA nor the pricing — one pool per pair).
- amm_create_pool_plan: canonicalizes the pair, moving amounts and user
holdings as one unit so each (vault, holding, amount) triple names the same
token, then emits the fixed 11-account NewDefinition plan (only the user
a/b and fresh LP holdings sign).
Module (AmmModuleImpl):
- liquidityQuote(request): thin preview wrapper, normalizes ids to hex.
- createPool(request, fresh_lp_id): a new pool always needs a fresh LP
holding, so an empty fresh_lp_id returns requiresFreshLp without
submitting; otherwise builds the plan and submits, returning a hex
transactionId.
