Derives a pool's PDA from the AMM program id and the two token ids —
compute_pool_pda(amm_program, canonical(token_in, token_out)) — returning
{ poolId }. Tokens may be given in either order; the op canonicalizes.
Unlike swap_pair, which derives the whole pair account-set (including the
current-tick PDA, which depends on config.twap_oracle_program_id and so
requires reading the config account), the pool address depends only on the
program id and the token pair. So a caller that just needs to locate and
read the pool can skip the config read entirely.
Exposed as the amm_pool_id C ABI export. Additive — no existing op changes.
It backs the config-free pool lookup the upcoming swap-quote path needs (and,
later, resolvePoolAccount).
