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

首先检查 graph-node 和 indexer-agent 的日志输出，尤其是 packages/indexer-common/dist/graph-node.js 和 packages/indexer-common/dist/errors.js，然后调查 entityCount 约束相关的 rewind 和索引状态路径。重现 graphman 的 rewind 或 drop 场景，并确认 graph-node 恢复同步且 indexer-agent 不再进入 crashloop。

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?
