refactor: replace UUID4 with content-addressed IDs for stored entities

- audit_id (harmony): sha256(canonical entry JSON) — deterministic, idempotent - tag_id: sha256({repo_id, commit_id, tag}) via compute_tag_id() in store.py - release_id: sha256({repo_id, tag, commit_id}) via compute_release_id() in store.py - op_id (op_log): sha256(canonical op fields) — deterministic per actor+lamport+domain

Removes uuid imports from harmony.py, tag.py, release.py, op_log.py. Updates AuditEvent docstring, op_id length assertion in test_op_log.py. Fixes _short_id test imports in test_rebase_supercharge and test_release_supercharge to use short_id from muse.core._types instead of non-existent private helpers.
