- Added `argon2` v0.5 dependency to `spire_ffi/Cargo.toml` - Implemented `argon2id_derive` FFI function in `spire_ffi/src/lib.rs` with C-ABI. - Added Deno FFI binding `deriveArgon2idKey` in `server/spire_ffi.ts` with `nonblocking: true` to prevent stalling the event loop. - Pre-allocates output buffer on the Deno side as the standard FFI pattern. - Included fallback mock behavior when `libspire_ffi.so` is not loaded, returning a 32-byte 0xaa filled array. - Updated unit tests in `server/spire_ffi.test.ts` to test mock usage and successful generation.
