[WIP] Review migration progress to Rust for fastforge

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

继续对 fastforgedev/fastforge 迁移到 Rust 过程中未完成的功能进行梳理，重点包括：1. 检查与 fastforgedev/fastforge 仓库相比，libnativeapi/nativeapi 仓库在 main 分支下是否有类似迁移目标、路线图或相关 Rust/原生实现的迁移进度说明文档（如 MIGRATION_ROADMAP.md 或 README.md 介绍迁移）；2. 检查项目主目录、crates 目录、packages 目录下的主要内容和代码结构；3. 检查是否有迁移残留的 Dart/Flutter 代码，以及对应的 Rust/native 实现迁移状态。给出结构化总结，指出未迁移的核心功能、进度及与 fastforgedev/fastforge 迁移模式的异同。
