jif a397079287 Preserve MCP resource origins across compaction (#39192) ...

## Why

Compaction can remove the tool-call events that associate an MCP app widget with
the tool, account, and URI needed to authorize later resource reads.

## What changed

- Store a bounded MCP resource-origin checkpoint with each compacted rollout.
- Restore the checkpoint when resuming a session so existing widgets remain
  readable after compaction and restart.
- Discard saved origins when rollback rewrites history across the compaction
  boundary, and reject oversized or invalid checkpoints during restoration.

## Testing

- Extend the app-server MCP resource-origin test to compact a paginated thread,
  continue the conversation, and read the original widgets before and after a
  restart.
- Verify rollback clears provenance that no longer matches retained history.
