chore: restore .claude commands, agents, helpers & skills (lost in 1df208d)

Restores the entire .claude/ infrastructure that was accidentally deleted
in commit 1df208d ('feat(timeline): add pulse animation for in-flight drag
mutations'). Recovered via git checkout 1df208d^.

Restored:
- .claude/commands/ (gitlooper, sparc/, github/, automation/, monitoring/,
  optimization/, hooks/, plan, implement, research, review, perf, visualaudit)
- .claude/agents/ (core/, github/, sparc/, v3/, swarm/, templates/, ...)
- .claude/helpers/ (41 scripts incl. hook-handler.cjs, statusline.cjs)
- .claude/skills/ (20 skills incl. sparc-methodology, github-*, v3-*)
- .claude/settings.json (hooks configuration)

Also updated all CapaKraken → Nexus references in affected command files.

+# Check Coordination Status
+
+## 🎯 Key Principle
+
+**This tool coordinates Claude Code's actions. It does NOT write code or create content.**
+
+## MCP Tool Usage in Claude Code
+
+**Tool:** `mcp__claude-flow__swarm_status`
+
+## Parameters
+
+```json
+{
+  "swarmId": "current"
+}
+```
+
+## Description
+
+Monitor the effectiveness of current coordination patterns
+
+## Details
+
+Shows:
+
+- Active coordination topologies
+- Current cognitive patterns in use
+- Task breakdown and progress
+- Resource utilization for coordination
+- Overall system health
+
+## Example Usage
+
+**In Claude Code:**
+
+1. Check swarm status: Use tool `mcp__claude-flow__swarm_status`
+2. Monitor in real-time: Use tool `mcp__claude-flow__swarm_monitor` with parameters `{"interval": 1000}`
+3. Get agent metrics: Use tool `mcp__claude-flow__agent_metrics` with parameters `{"agentId": "agent-123"}`
+4. Health check: Use tool `mcp__claude-flow__health_check` with parameters `{"components": ["swarm", "memory", "neural"]}`
+
+## Important Reminders
+
+- ✅ This tool provides coordination and structure
+- ✅ Claude Code performs all actual implementation
+- ❌ The tool does NOT write code
+- ❌ The tool does NOT access files directly
+- ❌ The tool does NOT execute commands
