Improve developer onboarding: missing setup steps and .mcp.json config

[s3bc40]

Hey CodSpeed team 👋

Really glad that I discovered this repo from LinkedIn, I was really curious to test it out by following your contributing file.

MCP config

I encountered a minor issue while running Claude Code just for some contexts, with the .mcp.json at the root of the project:

{
  "mcpServers": {
    "CodSpeed": {
+      "type": "http",
      "url": "https://mcp.codspeed.io/mcp"
    }
  }
}

I already encountered this error in a recent side project. Just following Claude MCP doc to fix it after I ran /doctor.

First setup after cloning

After a fork and cloning the repo, I encountered errors after cargo build and then cargo test.
It was just some missing steps on my side, but required to run the two previous cmd with success.
Prerequisites are rustup and git lfs installed before running those cmds:

git submodule update --init --recursive
git lfs install
git lfs pull

I will propose a PR related to this issue so you can track it easily, but feel free to close it if not relevant 👍
