fix(mcp): correct server.json schema compliance for registry publishing

- Change registry_type to registryType (camelCase as per schema)
- Change file_sha256 to fileSha256 (camelCase as per schema)
- Shorten description from 170 to 88 characters (within 100 char limit)
- Remove unsupported 'status' field from server.json

Fixes 422 validation errors when publishing to MCP Registry.
The registry API requires camelCase field names and enforces a 100
character limit on descriptions.
