Git Worktree Integration

Priority: MEDIUM — Enhances workflow safety

Purpose

Automatically create a git worktree when starting a workflow, so all changes happen on an isolated branch. If the workflow fails, discard the worktree — zero damage to the main codebase.

When to Use

• Auto-activate: When workflow:start is called and AF_WORKTREE=true is set
• Manual: User says "use a worktree" or "work in isolation"
• Skip: Quick bug fixes, config changes, single-file edits
