Add custom user agent for Meilisearch MCP server

- Add client_agents parameter to identify meilisearch-mcp in requests
- Create __version__.py module to centralize version information
- Add tests to verify user agent is properly configured
- Helps with analytics tracking and debugging

This implementation uses the Meilisearch Python SDK's built-in
client_agents parameter to identify requests from the MCP server.
