Parse user arguments, then launch a single background Agent that runs the entire pipeline (analyze → AI insights → build → open browser). The user can continue working while the dashboard is being generated.

Help

ONLY show help if the user's argument literally contains the word "help" (e.g. /usage-view help). If no argument or any other argument is given, SKIP this section entirely and proceed to launching the agent.

If the user provides "help" as argument, show usage summary and stop:

/usage-view — Interactive HTML usage dashboard

Options:
  (nothing)       All projects, last ~1 month
  current         Current 5-hour window only (fast, no AI analysis by default)
  last N days     Analyze last N days only
  locale XX       Force language (e.g. locale ja). Default: system language → en fallback
  no ai           Skip AI analysis for faster rendering (no LLM cost)
  ai              Force AI analysis (use with "current" to override its default)
  help            Show this help
