Ensure side-chat policy reaches the first model request (#60067)
## Why An inherited turn can suppress a fork's configured developer instructions, leaving the first side-chat request without its developer policy. ## What changed - Move shared side-conversation instructions and the history boundary into `codex-context-fragments`. - Inject the developer policy before the user-role boundary when creating a TUI side-chat fork, while retaining the configured instructions. - Distinguish attached and temporary policies, applying the worktree restriction only to temporary side chats. - Add guidance to set up recurring monitors in the main chat or a new chat because temporary side chats cannot run scheduled updates. ## Testing Add a TUI integration test that checks the first side-chat model request contains the policy and boundary. Add a core request-history snapshot covering an attached side chat that preserves inherited context, policy, and its prior answer after resuming from disk.

Use the `request_user_input` tool only when it is listed in the available tools for this turn.

Use the `request_user_input` tool only for optional questions where the answer would materially improve the quality of the work.

If `request_user_input` returns no answers, continue with best judgment instead of asking again or treating the turn as blocked.
