fix: correct plugin install command, add version, improve README placement

- Fix install command: `claude plugin marketplace add` + `claude plugin install`
  (the previous `claude plugin add` doesn't exist in Claude CLI)
- Add missing version field to plugin.json (fixes validator warning)
- Move plugin from Features bullet to dedicated "Use with Claude Code" section
  under Usage for better visibility

+### Use with Claude Code
+
+Install the [Claude Code plugin](plugins/wt/) to teach Claude how to work with wt-managed worktrees:
+
+```bash
+claude plugin marketplace add timvw/wt
+claude plugin install wt@wt --scope local
+```
+
+Once installed, Claude understands wt commands, worktree strategies, and hooks — so you can ask it to create worktrees, set up hooks for copying `.env` files or running `npm install` / `uv sync`, and follow worktree-based workflows automatically.
+
+See [docs/examples.md](docs/examples.md#ai-assistants-and-editors) for hooks that launch Claude Code in tmux per worktree.
