.github/lsp.json reports issues, while identical config works OK in ~/.copilot/lsp-config.json

Describe the bug

When running /lsp test myserver with .github/lsp.json, I get a message saying it's not there, blocking me from providing it as a convenient default for my teammates.

Moving .github/lsp.json to ~/.copilot/lsp-config.json makes it work immediately.

Affected version

0.0.406

Steps to reproduce the behavior

1. Put the below in .github/lsp.json

  "lspServers": {
    "gopls": {
      "command": "gopls",
      "args": ["serve"],
      "fileExtensions": {
        ".go": "go"
      }
    }
  }
}

2. Run /lsp show to see:

● LSP Server Status:


  Project-configured servers:
    • gopls: (.go)

3. Run /lsp test gopls and you'll get:

✗ Server "gopls" not found. Available: (none)

4. Move the exact file to the global conf: mv .github/lsp.json ~/.copilot/lsp-config.json
5. Run /lsp test gopls and it passes:

● ✓ Server "gopls" started successfully!

    PID: 31643
    Spawn time: 7ms

  Server was killed after successful test.

Expected behavior

I'd expect the config to work OK in .github/

Additional context

Linux, tested on both bash and zsh
