[Bug] Rewinding a subgraph causes a constraint violation in graph-node that in turn causes indexer-agent to crashloop

まず graph-node と indexer-agent のログ出力、特に packages/indexer-common/dist/graph-node.js と packages/indexer-common/dist/errors.js を確認し、次に entityCount 制約に関連する rewind と indexing-status の経路を調査します。graphman の rewind または drop シナリオを再現し、graph-node が同期を再開し、indexer-agent が crashloop に陥らなくなることを確認します。

Bug report

graph-node:v0.34.1
indexer-agent:v0.20.22

Activities that were undertaken before observing this bug:

1. Cleared call_cache for Arbitrum as part of a complex subgraph sync performance troubleshooting exercise via psql
2. Rewound a specific problematic subgraph, Silo Finance Arbitrum, QmTMKqty5yZvZtB3SwzXUG92aZUH1YQw3VjByGw4wgaMhW to block 1 using graphman
3. Observed the above subgraph syncing to ~130m blocks, then stalled.
4. Checked graph-node logs and found related error (see log output)
5. Observed indexer-agent complaining about same issue and crash looping - cannot use the agent at all right now to manage subgraphs (see log output)

IMPACT: Production Indexer at risk; we cannot manage our online and offline allocations while we have this issue - ideally need a temp fix for the specific symptoms. Would graphman drop resolve the issue? Would the graph-node and indexer-agent be able to handle that and start syncing the sub again from scratch given this is a subgraph in flight with live allocations?
