feat(migrate): Phase 2 — migrate legacy dirs to unified object store

- migrate() deletes .muse/commits/ and .muse/snapshots/ after writing all content to the unified object store (guarded by dry_run flag) - init_repo_dirs() no longer creates commits_dir or snapshots_dir - Added 12 TDD tests in test_phase2_legacy_store_migration.py - Updated test_code_migrate.py helpers to read from object store instead of the now-deleted legacy directories
