[FEATURE] Official usage analytics dashboard for Max Plan subscribers

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Claude Code currently only shows weekly usage limits with no historical data or trends.
As a Max Plan subscriber paying $330/month (two accounts), I need better visibility into my usage.

Current limitations:

• No historical usage patterns (daily/weekly/monthly trends)
• No breakdown by model, project, or session
• No predictive insights (when will I hit my limit?)
• No cost analysis or token consumption details

Current Workaround

Many users rely on third-party tools like ccusage (10k+ GitHub stars) to analyze local JSONL files. While helpful, paying customers shouldn't need external tools for basic usage visibility.

Proposed Solution

An official dashboard (web or CLI) providing:

1. Usage graphs - Daily/weekly/monthly token consumption trends
2. Model breakdown - Cost analysis by Opus, Sonnet, Haiku
3. Project analytics - Per-project/session usage breakdown
4. Alerts - Notifications before hitting limits (e.g., 80% warning)
5. Comparison (optional) - Anonymous benchmarks with similar users

Priority

Medium - Important for paying customers

Feature Category

Usage reporting / Analytics

Use Case Example

As a Max Plan subscriber, I want to:

1. See my usage trend over the past month
2. Understand which projects consume the most tokens
3. Get notified before hitting weekly limits
4. Make informed decisions about plan optimization
