worktree command to quickly make, manage and remove git worktrees

I've been using worktrees a ton lately thanks to Claude Code. works pretty well, but interacting with worktres is also a lengthy command to do correctly and I never remember the right syntax. very git-friendly style problem

worktrees are great for running parallel Claude Code session from a single git checkout: https://docs.claude.com/en/docs/claude-code/common-workflows#run-parallel-claude-code-sessions-with-git-worktrees

new workflow command:

• makes & tears down consistently-named worktrees $dirname-$branch
• autocomplete branch name (in .profile)
• make worktree from remote branch
• updated README
