Emdash v1.2.2

This release adds Plan mode to Codex chat and improves remote development over Tailscale SSH, along with more reliable agent launching on Windows.

Highlights

• Codex ACP conversations can switch between Default and Plan modes directly from the chat composer, with the selection remembered across sessions.

Fixes

• Remote workspaces can connect over Tailscale SSH now that Unix socket forwarding works with compatible servers that use a non-OpenSSH identification banner.
• Windows preserves native command lines when launching .cmd agent shims, so agents such as Pi start correctly when arguments contain spaces or quotes.
• Saved ACP configuration options are cleared when an agent no longer supports them, preventing stale selections from being reapplied.
