Server-side SwapExactOutput submission, mirroring the exact-in path. The
swap_exact_out_plan FFI op resolves the pool via the shared derive_pair,
encodes amm_core::Instruction::SwapExactOutput { exact_amount_out,
max_amount_in, deadline }, and returns the same four tx-submission fields as
swap_exact_in_plan (programId, accountIds, signingRequirements, instruction)
in the identical fixed 8-account IDL order — only the user's input holding
signs. Recoverable domain failures (same_token_pair, config_unavailable) go
through the FFI envelope as Err. C export amm_swap_exact_out_plan (cbindgen
header regenerated).
The module swapExactOutput(defA, defB, userIn, userOut, amountOut, maxIn,
deadline) method reads the AMM config, calls the op, and submits the plan via
send_generic_public_transaction, returning the tx hash (empty string on
failure). Same argument conventions and I/O-free split as swapExactInput.
Not yet wired into AmmUiBackend/QML — the SwapCard rewire is a follow-up. The
existing swap UI path is untouched, so nothing breaks.
