v0.6.0

New Features

• OpenCode Zen balance monitor — New zen-balance widget showing your Zen account balance in Waybar. Uses browser cookies, same as Claude/Codex modules. (PR #5 by @Trojanku)
• Interactive module selector — waybar-ai-usage setup now shows a TUI checklist to pick which modules to enable. Also available non-interactively via --modules claude,codex,zen.
• Auto-open login page on auth errors — When Claude, Codex, or Zen returns HTTP 401/403, the module automatically opens the login page via xdg-open (with 10-minute cooldown to avoid spam).

Bug Fixes

• Copilot 404 classified as "Net Err" — The GitHub billing API requires a fine-grained PAT with Plan (read) permission. 404 responses are now correctly shown as "Auth Err" with guidance on creating the right token.
• Zen balance parsing — Prioritize JS state object pattern (balance:N) over legacy HTML comment patterns for more reliable extraction.

Other

• Add CLAUDE.md project guide for AI-assisted development
• Zen module config/style added to example templates
