Implement WebAssembly version using Rust for browser execution

[konard]

Summary

This PR implements issue #12 by adding a complete WebAssembly version of the link-cli tool using Rust, allowing users to execute link manipulation operations directly in web browsers.

🚀 Key Features

• Full WebAssembly Implementation: Complete Rust-based port with wasm-bindgen for JavaScript interop
• Browser-Native Execution: Runs entirely client-side without server dependencies
• Multiple Build Targets: Web browsers, Node.js, and bundlers (Webpack, Rollup, etc.)
• Interactive Web Demo: Live demonstration with pre-built examples at /www/index.html
• Comprehensive Testing: Automated CI/CD pipeline with browser and Node.js testing

🔗 LiNo Protocol Support

The implementation includes a robust LiNo parser supporting all core operations:

• Create: () ((1 1)) - Create new links
• Read: ((($i: $s $t)) (($i: $s $t))) - Query existing links
• Update: ((1: 1 1)) ((1: 1 2)) - Modify existing links
• Delete: ((1 1)) () - Remove links
• Wildcards: ((* *)) () - Delete all links

📦 Distribution

• NPM Package: Available as clink-wasm for Node.js usage
• Web Package: Direct browser import via ES modules
• GitHub Pages: Automated demo deployment

🧪 Testing & Quality

• Rust unit tests for core functionality
• WebAssembly integration tests in browsers
• Automated builds for all target platforms
• Compatibility testing with Protocols.Lino specification

📋 API Usage

import init, { Clink } from 'clink-wasm';

await init();
const clink = new Clink();

const options = JSON.stringify({
    db: "memory",
    changes: true,
    after: true
});

const result = clink.execute("() ((1 1))", options);
console.log(JSON.parse(result).output);

🔄 Version Update

Project version updated to 2.3.0 across:

• C# project (Foundation.Data.Doublets.Cli.csproj)
• Rust/WASM project (Cargo.toml)
• NPM package (package.json)

Test Plan

• Rust unit tests pass (cargo test)
• WebAssembly builds successfully for all targets
• Browser demo works with all example operations
• Node.js integration functions correctly
• CI/CD pipeline builds and tests automatically
• Version consistency across all package files
• Documentation complete and accurate
