mycel v0.19.4

mycel v0.19.4

Daemon-only patch release for Raft replay/idempotency recovery after restart or upgrade.

Fixed

• Fixed automation Raft replay so stale/superseded invocation updates are no-ops when durable invocation state already dominates the replayed command, preventing startup readiness failures from stale automation invocation update.
• Fixed graph Raft replay so superseded stale graph commits repair applied-command markers instead of surfacing replay-time graph conflict errors, while preserving live conflict behavior.
• Serialized graph applied-command marker persistence to avoid concurrent marker write temp-file races during replay/idempotency repair.

Compatibility

• Daemon-only patch release.
• Public protobuf/API bindings remain compatible with mycel-api v0.19.0.
• No SDK, Console, or Lab release required for API compatibility.
