v2.1.0

The usage readout is now /multiclaude:quota.

Changed

• Renamed the usage skill to quota so its slash command is
  /multiclaude:quota instead of /multiclaude:usage. The old name shadowed
  Claude Code's built-in /usage command and was confusing to invoke. The
  readout, output format, and underlying wallet sources are unchanged — only the
  command name. References to Claude Code's first-party /usage (the source of
  the CLAUDE utilization bars) are intentionally kept as-is.
• Moved skills/usage/usage.mjs → skills/quota/quota.mjs; updated the
  setup health check, the orchestrate §0 fallback pointer, the README, and the
  plugin/marketplace manifest descriptions to match.

Migration

• /multiclaude:usage no longer exists — use /multiclaude:quota. Restart
  Claude Code after updating so the renamed skill is picked up.
