Swap websocket lib

[Sayan-]

Overview

As I spent more time with this lib I noticed a few things I wasn't a huge fan of (no concurrency, ~incomplete compression, some surprises with deadlining). Opt'ing to swap over to the coder/websocket library that I've used successfully in prod for ~years

Testing

Built docker + unikernel images. Tested the unikernel images against the wip test suite

TL;DR

Replaced the gorilla/websocket library with coder/websocket for handling Chrome DevTools connections.

Why we made these changes

The previous library had limitations regarding concurrency, compression, and connection deadlining. The coder/websocket library is a more robust, production-proven alternative that resolves these issues.

What changed?

• Updated go.mod and go.sum to swap the websocket libraries.
• Refactored server/lib/devtoolsproxy/proxy.go to use the new coder/websocket API for accepting, dialing, and managing connections.
• Updated tests in server/lib/devtoolsproxy/proxy_test.go to align with the new implementation.
• Replaced echo -n with printf in server/cmd/api/api/process_test.go for better test compatibility.
