Crate rustledger_ffi_wasi 

Slimmed FFI-support helpers for the rustledger WASI component FFI.

Phase 5 (#1419) is complete

This crate used to expose a wasip1 JSON-RPC 2.0 embedding API (a server binary in main.rs + a jsonrpc router) plus a Directive → JSON output DTO. Both are gone: the JSON-RPC surface was retired earlier in Phase 5 (#1419) now that the typed WASI Preview 2 / Component Model binding, rustledger-ffi-component (#1384), is the default embedding path (default in rustfava as of Phase 4); the output DTO was removed once the component switched to converting core→WIT directly.

What remains is a library only of FFI-support glue the component reuses: the loader orchestration (helpers), the WIT-input construction path (input_entry_to_directive + the Input* types) and directive hashing (compute_directive_hash). These survivors are deliberately FFI glue kept OUT of the core rustledger-loader crate, so the crate is retained slimmed rather than relocated or deleted (the “retained … document the decision” outcome of #1419 item 6).
