v2.0.1 - Safer ship workflow

Highlights

• Safer ship workflow: xdev now enters an implementation worktree before full-dev produces design, visual, plan, or implementation commits.
• Base branch protection: ship flows now stop before publishing from main or master.
• Cleaner worktree lifecycle: implementation worktrees copy root .env* / .envrc files, remind users to reinstall ignored dependencies, and clean up after ship.
• More portable workflow snippets: state-file updates now use Python instead of macOS-only sed -i '' commands.
• Better release discoverability: the project now has a root CHANGELOG.md, a VERSION file, and README links to release notes.

Upgrade notes

• Current version: v2.0.1.
• Existing users can update with cd ~/.claude/skills/xdev && git pull.
• Windsurf users should rerun bash ~/.claude/skills/xdev/bin/install.sh windsurf if new or renamed workflow files appear in future releases.
