r4bbit f5ff9b829f refactor(apps/amm): move the amm_client crate into modules/amm/ffi as amm_ffi
After the amm_module refactor, this crate is linked only by the module (the
UI delegates to modules().amm_module and links nothing), so its home under
apps/amm/ and the name "client" were both misnomers: it's the AMM business
logic the module wraps, reached across an FFI boundary — the same relationship
logos_execution_zone has with wallet_ffi. Co-locate it with the module that
owns it and name it for that role.

The FFI surface is unchanged — the exported functions are already amm_* (not
amm_client_*) — so only the crate, directory, generated header, dylib, and
package names move. The module's call sites are untouched; it just includes the
renamed header.

- apps/amm/client → modules/amm/ffi (git-tracked rename; history preserved)
- crate amm_client → amm_ffi: package name, include/amm_ffi.h, libamm_ffi.dylib,
  AMM_FFI_H guard, build.rs output path, tests/public_api.rs import
- workspace member path + Cargo.lock
- flake.nix: pname, -p, header-copy path, dylib install_name, packages.amm_ffi,
  ammModuleOutputs externalLibInputs, DYLD wrapper
- modules/amm: metadata external_libraries, CMakeLists EXTERNAL_LIBS, impl
  #include + comments, README, flake note
- apps/amm/flake.nix: drop the now-dead amm_client external-lib input (the UI
  links no external lib of its own)

Resulting layout:
  modules/amm/
    src/   # C++ module  (amm_module_impl.{h,cpp})
    ffi/   # Rust crate  amm_ffi  (Cargo.toml, src/, include/amm_ffi.h)

# NOTE: like apps/amm, this flake is NOT built standalone. The amm_ffi
# crate this module links (the Rust JSON-FFI brain) lives in the repo-root
# flake, and referencing it from here would require a hardcoded `git+file://`
# path or a `path:../..` input — the latter fails flake evaluation because this
# dir is copied into the Nix store as its own flake root, so `../..` can't
# escape it. Instead, the repo-root flake.nix builds this module directly
# (src = ./modules/amm) and resolves amm_ffi via `self`. Build it from
# the repo root:
# nix build .#amm-module
