Add npm homepage and bugs metadata

[sh962214-hub]

The published @socketsecurity/mcp@0.0.18 package currently exposes repository metadata but not npm homepage or bugs metadata:

npm view @socketsecurity/mcp@0.0.18 name version homepage repository bugs --json

Observed result includes only:

{
  name: @socketsecurity/mcp,
  version: 0.0.18,
  repository: {
    url: https://github.com/SocketDev/socket-mcp,
    type: git
  }
}

Expected metadata would point npm users to the README and issue tracker, for example:

• homepage: https://github.com/SocketDev/socket-mcp#readme
• bugs.url: https://github.com/SocketDev/socket-mcp/issues

I prepared the one-file manifest patch here, but GitHub would not let this account open a cross-fork PR into SocketDev/socket-mcp:

• fork PR with patch: chore: add npm metadata links sh962214-hub/socket-mcp#1

Local validation:

• metadata smoke check for homepage, bugs, and repository
• git diff --check
