Generalize migration guide for any GRASP implementation

- Rename guide: migrate-ngit-relay-to-ngit-grasp.md → migrate-to-ngit-grasp.md
- Remove ngit-relay and relay.ngit.dev specific references
- Use generic terminology: source/target relay, current implementation
- Add Compatibility section explaining requirements
- Update examples to be implementation-agnostic
- Update script comments to reference GRASP relay (not ngit-relay)
- Update README.md to link to the new guide

Scripts already work with any GRASP implementation via parameters.
