v1.9.0

Completes the orchestrate → multiclaude rename and makes the setup step real.

Added

• /multiclaude:setup command. New skills/setup skill wrapping
  scripts/setup.sh — the deploy docs and the usage skill already referenced
  /multiclaude:setup, but no such command existed. Verifies codex/agy
  (installed + authenticated), python3/find/node, companion plugins, the
  wallet-headroom hook, and ccusage; prints an exact fix: for anything missing.

Changed

• Ship the bootstrap settings inside the plugin. Moved
  setup/settings.json (repo root, not distributed) →
  multiclaude/setup/settings.json, so a plugin-only install can find the
  canonical ~/.claude/settings.json at ${CLAUDE_PLUGIN_ROOT}/setup/.
  scripts/setup.sh now points its fix messages at that shipped path.
• Finished the rename drift. setup/settings.json enabledPlugins, the
  README (orchestrate/ dir, /orchestrate command, orchestrate@multiclaude
  enable key, install name), and the manifest descriptions now all say
  multiclaude / multiclaude@multiclaude instead of the dead orchestrate
  name.
