🛠️ Fixes

Fixed bug where /fork on a local workspace would create a broken worktree workspace
Fixed two bugs related to previousResponseId handling with OpenAI models over Mux Gateway
- gpt-5.2-codex should now be usable over Gateway
Fixed incorrect context window stats for gpt-5.2-codex, removing "output reserve" indication which was added with bad underlying reasoning
Improved New Project flow
- If project directory doesn't exist, Mux will transparently create it for you
- If you enter a project name like "cool-vibe-project", Mux will place it into "~/.mux/projects/cool-vibe-project" instead of "/cool-vibe-project"
  - Psychos out there can still place projects at the root by entering "/cool-vibe-project" in the New Project flow
