Watch Claude Code and Codex work inside dsh

Key features

• The human half is the split viewa seat bar, and one pane per seated agent.
• Enter is typed separately from the message.
• The workspace is never chosen by the browser.
• The PTY comes from the harness's subprocess seam (ctx.subprocess.spawnTerminal), so this package inherits its credential scrub and process-tree teardown and ships no compiled addon.
• The pane is a real terminal — colour, cursor addressing, the product's own TUI — because the plugin carries the CLI's bytes rather than reimplementing its surface.
