Add contributing guidelines to prevent seed.json PRs (#1079)
<!-- Provide a brief summary of your changes -->

## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
We've been receiving numerous PRs from authors attempting to publish
their MCP server by adding entries to `data/seed.json`. This is not the
correct approach as servers should be published using the
`mcp-publisher` CLI tool.

Many of these PRs appear to be AI-generated so the existing docs aren't
being surfaced effectively. This PR adds explicit guidance in the files
that AI coding assistants actually read:
- `CONTRIBUTING.md` - shown by GitHub when opening new PRs; widely
ingested by AI tools
- `.github/copilot-instructions.md` - read by GitHub Copilot
- `CLAUDE.md` - read by Claude Code and Claude on github.com

## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->

## Breaking Changes
<!-- Will users need to update their code or configurations? -->

## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update

## Checklist
<!-- Go over all the following points, and put an `x` in all the boxes
that apply. -->
- [ ] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [ ] My code follows the repository's style guidelines
- [ ] New and existing tests pass locally
- [ ] I have added appropriate error handling
- [ ] I have added or updated documentation as needed

## Additional context
<!-- Add any other context, implementation notes, or design decisions
-->

# Contributing to the MCP Registry
Thank you for your interest in contributing!
## Want to publish an MCP server?
**Do NOT open a pull request to add your server to `data/seed.json`.**
The `data/seed.json` file is seed data used only for local development. Modifying it will not publish your server to the registry.
To publish an MCP server, use the official `mcp-publisher` CLI tool. See the [publishing quickstart guide](docs/modelcontextprotocol-io/quickstart.mdx) for step-by-step instructions.
## Contributing to the registry codebase
We welcome contributions to the registry itself! Here's how to get started:
### Communication channels
We use multiple channels for collaboration - see [modelcontextprotocol.io/community/communication](https://modelcontextprotocol.io/community/communication).
Often (but not always) ideas flow through this pipeline:
- **[Discord](https://modelcontextprotocol.io/community/communication)** - Real-time community discussions
- **[Discussions](https://github.com/modelcontextprotocol/registry/discussions)** - Propose and discuss product/technical requirements
- **[Issues](https://github.com/modelcontextprotocol/registry/issues)** - Track well-scoped technical work
- **[Pull Requests](https://github.com/modelcontextprotocol/registry/pulls)** - Contribute work towards issues
### Development setup
See the [README](README.md#quick-start) for prerequisites and instructions on running the server locally.
### Running checks
```bash
# Run lint, unit tests and integration tests
make check
```
Run `make help` for more available commands.
