AddRoute now updates an existing route if one already exists for the same (listener, hostname) pair, instead of returning AlreadyExists. This makes repeated deploys idempotent — the MCP agent can register routes on every deploy without needing to remove them first. - DB: INSERT ... ON CONFLICT DO UPDATE (SQLite upsert) - In-memory: overwrite existing route unconditionally - gRPC: error code changed from AlreadyExists to Internal (for real DB errors) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
