Sameh Abouelsaad 9dce815daa feat: Add basic project structure and initial crates

- Added basic project structure with workspace and crates:
  `kvstore`, `vault`, `evm_client`, `cli_app`, `web_app`.
- Created initial `Cargo.toml` files for each crate.
- Added placeholder implementations for key components.
- Included initial documentation files (`README.md`, architecture
  docs, repo structure).
- Included initial implementaion for kvstore crate(async API, backend abstraction, separation of concerns, WASM/native support, testability)
- Included native and browser tests for the kvstore crate

kvstore: Async Key-Value Store for Native and WASM

kvstore provides a runtime-agnostic, async trait for key-value storage, with robust implementations for both native (using sled) and browser/WASM (using IndexedDB via the idb crate) environments.

Features

Unified async trait: Same API for all platforms. Methods: get, set, remove, contains_key, keys, clear.
Native backend: Uses sled for fast, embedded storage. Blocking I/O is offloaded with tokio::task::spawn_blocking.
WASM backend: Uses IndexedDB via the idb crate for browser storage. Fully async and Promise-based.
Error handling: Consistent error types across platforms.
Conditional compilation: Uses Cargo features and cfg to select the backend.

Usage

Add to your Cargo.toml:

[dependencies]
kvstore = { path = "../kvstore" }

Example

use kvstore::{KVStore, NativeStore};

#[tokio::main]
async fn main() {
    let store = NativeStore::open("/tmp/mydb").unwrap();
    store.set("foo", b"bar").await.unwrap();
    let val = store.get("foo").await.unwrap();
    println!("Got: {:?}", val);
}

For WASM/browser, use WasmStore and run in a browser environment.

Testing

Native

cargo test -p kvstore --features native

WASM (browser)

cd kvstore
wasm-pack test --headless --firefox --features web

Architecture

See ../docs/Architecture.md for full design details.
