feat: make simple node struct that works with QUIC (#39)

* chore: implement P2P Node with QUIC support and basic echo functionality

- Added dependencies for QUIC, cryptograph in Cargo.toml.
- Created a new module `node` to encapsulate the P2P node functionality.
- Removed the default main function as the application structure is now modular.
- Implemented the `Node` struct with Ed25519 key management, QUIC endpoint setup, and peer management.
- Added methods for connecting to peers, adding/removing peers, and handling self-signed certificates.
- Implemented SPKI pinning for enhanced security during peer connections.
- Added a smoke test for establishing a QUIC connection and echoing messages between two nodes.

* chore: remove TODO in Node implementation and .DS_Store and .vscode to .gitignore

* feat: add anyhow dependency, add custom ALPN, zeroize copies after used, clean up API

Anyhow is now used as the standard way to handle errors. Node.rs now has a spawn_echo_server function. connect_to() is renamed to connect_to_spki() and take sin the spki cert instead of the DER cert. Add helper method to get SPKI from der. Make transport directory.

* chore: rebase starting-framework with dioxus project

* refactor: simplify connection handling in Node echo server

* refactor(frontend): simplify echo.rs

* fix(ci): update clippy command to exclude UI targets
