Chris Hayduk c9fac4dd5a Avoid holding metadata permit during cold resume config load (#42773) ...

## Why

Cold `thread/resume` configuration loading can call back into the host. Holding the global metadata permit during that work blocks unrelated thread metadata updates and MCP requests.

## What changed

- Release the metadata permit while loading configuration for a cold resume.
- Reacquire the permit and reload the resolved thread history before startup.
- Reload configuration when persisted metadata, settings, or the history working directory changed during the unlocked interval.
- Rejoin a thread that another request resumed concurrently, and avoid reopening threads that were archived or deleted.

## Testing

Add coverage for unrelated metadata and MCP requests during a blocked config load, concurrent resume mutations, and the extra history read required for non-local thread stores.
