The previous installation command didn't work because Claude Code
plugins require a marketplace manifest. This adds the marketplace.json
and updates install instructions to the correct two-step flow:
1. /plugin marketplace add jarrodwatts/claude-hud
2. /plugin install claude-hud@claude-hud
Also commits dist/ for plugin distribution since users can't run
npm build when installing via marketplace.
