- Move options.services.hive-c0re → options.hyperhive.c0re
- Add options.hyperhive.enable to auto-enable c0re + subsystems
- Add deprecation alias for services.hive-c0re.enable (backward compat)
- Update doc references in README, flake.nix, docs, harness-base.nix
- Simplifies config: 'hyperhive.enable = true' now enables everything
Existing operator configs using services.hive-c0re.enable will
continue to work but emit a deprecation warning. Aligns the option
namespace with the existing hyperhive.* family (matrix, forge, domain).
