feat: domain_command_registry — Phase 1 of muse#74 (SCR_01-03)

A dependency-free registry mapping a domain name to its dedicated CLI subcommand names (register_namespace/get_supported_commands), designed to replace the hardcoded supported_commands literal in `muse domains publish` (Phase 3).

- SCR_01: basic contract — unregistered name returns [], register then query returns the registered list. - SCR_02: idempotent re-registration — registering twice replaces, never appends or duplicates. - SCR_03: deterministic sorted output regardless of insertion order or input type (list, set, dict.keys() — the real shape argparse's _SubParsersAction.choices will pass in Phase 2).

Zero dependencies on app.py or any command module, by design — must be importable from domains.py without circular-import risk. 8/8 new tests pass, mypy clean.

Phase 1 of 4 — see muse#74 for the full plan. Registry is not yet wired into any real CLI namespace (Phase 2) or into `muse domains publish` (Phase 3).
