fix: resolve CI build failures in workspace config and WASM linking

- Remove nonexistent buttplug_client_conformance_test from
  default-members (leftover from another branch)
- Enable instant/wasm-bindgen feature when buttplug_server's wasm
  feature is active. Without this, the instant crate imports now() from
  a nonexistent env module. Release builds optimized away the dead code,
  but dev builds (--dev on CI) hit an undefined symbol linker error.
