Add SDK/version as User-Agent in HTTPClients

[bmehta001]

• Embeds SDK + version into the default User-Agent header for Http Client for C#/JS/Python/Rust
• Bump patch versions where necessary - not sure it's necessary for Rust
• Pull versions programmatically to avoid hardcoding
• Used genversion library for JavaScript and Reflection for C#
• Lint/add node_modules to .gitignore
• Tested C#, Rust, Python, and JS

PR Summary
The changes update the HTTP client implementations in Rust, C#, Python, and JavaScript to dynamically include the SDK version in the User-Agent header. This ensures consistent version reporting while also bumping the overall package versions.

• sdk/rust/src/client.rs: Updated the client builder to use the dynamic version from Cargo.
• sdk/cs/src/FoundryLocalManager.cs: Configured the C# client to extract the assembly version for the User-Agent header.
• sdk/python/foundry_local/client.py and new sdk/python/foundry_local/version.py: Modified the Python client to import and use the SDK version in its header.
• sdk/js/src/client.ts and new sdk/js/src/version.ts: Adjusted the JavaScript client and build script to inject the SDK version into the User-Agent header.
