v0.11.1

v0.11.1 — Project-level Incremental Cache for blocks --live

⚡ Performance

Add project-level incremental cache for blocks --live mode, reducing CPU usage by 68% when data is unchanged.

How it works:

• Tracks file state (ModTime + Size) per project directory
• Only reloads files that have actually changed
• Skips entirely when no changes detected (< 1ms)
• Per-project deduplication for efficient append-only JSONL handling
• Full project reload on file deletion for cache consistency

📊 Performance Metrics

Metric	Before	After	Improvement
CPU avg (30s)	26.7%	8.5%	-68%

📁 Files Changed

• internal/loader/project_cache.go — New incremental cache implementation
• internal/loader/project_cache_test.go — 9 unit tests
• internal/monitor/blocks_live.go — Integrated incremental cache into tick handler

What's New

📊 Usage Limits Display (blocks --live)

• New LIMITS section showing Claude API quota in real-time
• Displays session (5-hour) and weekly limits with progress bars
• Color-coded indicators: green (≤60%), yellow (60-90%), red (>90%)
• Shows reset times in local timezone
• Reads OAuth token from environment, credentials file, or macOS Keychain
• Graceful degradation: section hidden when no token or API unavailable

🔧 Fix Model Name Display for New Format

• Fixed truncated display for dateless model IDs (e.g. claude-opus-4-6, claude-sonnet-4-6)
• claude-opus-4-6 now correctly shows as Opus-4.6 instead of claude-opus-
• claude-sonnet-4-6 now correctly shows as Sonnet-4.6 instead of claude-sonne
• Existing dated formats (e.g. claude-haiku-4-5-20251001) remain unaffected

📸 Updated Screenshot

• Updated blocks --live monitor screenshot reflecting new LIMITS section

New Package

• internal/usage/ — Claude OAuth Usage API client with cross-platform token reading and 5-minute cache
