The open-in-editor feature now supports jumping to specific line numbers across different editors. GUI editors (like VS Code, Sublime) use their native line-jump flags, while terminal editors (like vim, nano) use +N syntax. The editor spawning handles both detached GUI processes and inline terminal editors with alternate screen management.
