Revert overselling of Claude Code plugin installation

The README was claiming one-command, zero-config installation, but actually requires: 1) marketplace add, 2) plugin install, 3) separate bd CLI installation. This revert tones down the promotional language to match reality.

Thanks to @jjshanks for catching this!
