Keyan Zhang b46a3801e4 Preserve parent tool declarations in prediction forks (#57287) ...

## What changed

Keep inherited incremental tool declarations in MCP-disabled prediction forks and `thread/sample` requests, and append a developer notice that MCP tools are unavailable. Skip tool declaration updates within the inherited context window; new windows still declare the current tools.

Add the default-enabled `prediction_preserve_parent_tools` feature flag and its configuration schema entries.

## Testing

Update core snapshots and app-server tests to cover inherited declarations, the MCP-unavailable notice, preservation across MCP refresh, and continued parent tool availability.
