- Remove isClaudeWeeklyWindow() suppression logic so absolute reset timestamps display for all provider windows
- Populate resetAt field in Codex (reset_at / reset_after_seconds), Gemini (resetTime), Minimax (remains_time), and Zai (nextResetTime) providers
- Enable fallback relative text generation for all windows when resetText is null but resetAt exists
- Add tests for resetAt extraction across Codex, Gemini, Minimax, and Zai providers
- Update UsageIndicator component tests to reflect that all windows now show absolute reset dates
