- Added `vanth_derive` crate with a procedural macro to automatically implement the `Vanth` trait for structs, including generics.
- Refactored `vanth` crate by removing obsolete `vanth.rs` file.
- Implemented `PartialEq` for `Ty` to enable comparisons with string values and another `Ty`.
- Added integration tests for deriving `Vanth` with generic parameters.
- Updated dependencies: added `quote`, `syn`, and `proc-macro2` crates.
- Added a new `vanth_cli` crate with `clap` command structure for `vanth fs open/save` commands.
- Removed `main.rs` from `vanth` crate as it is now a library without a binary target.
- Added `fs.rs` module and new structs `HashedValue`, `Value`, `Ty` with `Vanth` trait to support serialization.
- Updated `Cargo.toml` to include `clap` as a workspace dependency and added `vanth_cli` as a new crate.
- Added multiple dependencies (`anstream`, `anstyle`, `clap`, `heck`, etc.) in `Cargo.lock` to support the CLI.
- Created placeholder test files `tests/fs/mod.rs` and `tests/main.rs` in `vanth` crate for future use.
- Marked CLI command implementations with TODOs as functionality is not yet implemented.
