feat: Claude Code Monitor — lanes, pipelines and a merged workspace

Internal SmartGift build of a Claude Code monitoring dashboard.

Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.

Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.

Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.

+# Weekly Report
+
+Generate a comprehensive weekly productivity report from Agent Monitor data.
+
+## Input
+
+The user provides: **$ARGUMENTS**
+
+This may be:
+- "this week" or empty (default: current week Mon-Sun)
+- "last week" for the previous week
+- A date range: "2025-04-07 to 2025-04-13"
+
+## Procedure
+
+1. **Fetch weekly data** from `http://localhost:4820`:
+   - `GET /api/sessions?limit=200` — filter to target week (default sort: most recently updated first)
+   - `GET /api/analytics` — aggregated analytics
+   - `GET /api/pricing/cost` — cost data
+
+2. **Build the weekly report**:
+
+   ### 📊 Week at a Glance
+   | Metric | This Week | Last Week | Change |
+   |--------|-----------|-----------|--------|
+   | Sessions | N | N | ↑/↓ N% |
+   | Total Hours | N | N | ↑/↓ N% |
+   | Tokens Used | N | N | ↑/↓ N% |
+   | Total Cost | $X.XX | $X.XX | ↑/↓ N% |
+   | Completion Rate | N% | N% | ↑/↓ |
+
+   ### 🏆 Highlights
+   - Most productive day (by sessions completed)
+   - Longest session and what it accomplished
+   - Most used tools and any new tools adopted
+   - Notable achievements (complex tasks completed, errors resolved)
+
+   ### 📈 Daily Breakdown
+   | Day | Sessions | Hours | Cost | Completion |
+   |-----|----------|-------|------|------------|
+   For each day of the week with activity.
+
+   ### 🔧 Tool Usage Report
+   - Top 10 tools by invocation count
+   - Tools with highest error rate
+   - Tool usage distribution chart (text-based)
+
+   ### 💡 Productivity Insights
+   - Peak productivity hours
+   - Average session duration and trend
+   - Cost efficiency trend
+   - Model usage distribution
+
+   ### 🎯 Recommendations for Next Week
+   - Based on error patterns: what to improve
+   - Based on cost trends: optimization opportunities
+   - Based on tool usage: workflow suggestions
+
+## Output Format
+
+Professional report format with:
+- Executive summary (3 sentences max)
+- Structured tables with week-over-week comparisons
+- Emoji-prefixed section headers for scannability
+- Actionable recommendations in priority order
