We have two ways of loading conversation with a previous history. Fork conversation and the experimental resume that we had before. In this PR, I am unifying their code path. The path is getting the history items and recording them in a brand new conversation. This PR also constraint the rollout recorder responsibilities to be only recording to the disk and loading from the disk. The PR also fixes a current bug when we have two forking in a row: History 1: <Environment Context> UserMessage_1 UserMessage_2 UserMessage_3 **Fork with n = 1 (only remove one element)** History 2: <Environment Context> UserMessage_1 UserMessage_2 <Environment Context> **Fork with n = 1 (only remove one element)** History 2: <Environment Context> UserMessage_1 UserMessage_2 **<Environment Context>** This shouldn't happen but because we were appending the `<Environment Context>` after each spawning and it's considered as _user message_. Now, we don't add this message if restoring and old conversation.

Linux
Expects the binary containing codex-core to run the equivalent of codex debug landlock when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
