Fork agent sessions from terminal context menu (#3976)

- Add a terminal action to create a top-level workspace fork with captured agent context
- Pre-mark local and SSH agent trust before launching forked Codex/Cursor/Copilot sessions
- Use remote/Linux startup behavior for SSH and WSL forks, with Windows draft size fallback
- Cover fork prompt cleanup, launch behavior, remote trust writes, and dialog busy-state tests
