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.

+# Smart Agent Auto-Spawning
+
+## Purpose
+
+Automatically spawn the right agents at the right time without manual intervention.
+
+## Auto-Spawning Triggers
+
+### 1. File Type Detection
+
+When editing files, agents auto-spawn:
+
+- **JavaScript/TypeScript**: Coder agent
+- **Markdown**: Researcher agent
+- **JSON/YAML**: Analyst agent
+- **Multiple files**: Coordinator agent
+
+### 2. Task Complexity
+
+```
+Simple task: "Fix typo"
+→ Single coordinator agent
+
+Complex task: "Implement OAuth with Google"
+→ Architect + Coder + Tester + Researcher
+```
+
+### 3. Dynamic Scaling
+
+The system monitors workload and spawns additional agents when:
+
+- Task queue grows
+- Complexity increases
+- Parallel opportunities exist
+
+**Status Monitoring:**
+
+```javascript
+// Check swarm health
+mcp__claude -
+  flow__swarm_status({
+    swarmId: "current",
+  });
+
+// Monitor agent performance
+mcp__claude -
+  flow__agent_metrics({
+    agentId: "agent-123",
+  });
+```
+
+## Configuration
+
+### MCP Tool Integration
+
+Uses Claude Flow MCP tools for agent coordination:
+
+```javascript
+// Initialize swarm with appropriate topology
+mcp__claude -
+  flow__swarm_init({
+    topology: "mesh",
+    maxAgents: 8,
+    strategy: "auto",
+  });
+
+// Spawn agents based on file type
+mcp__claude -
+  flow__agent_spawn({
+    type: "coder",
+    name: "JavaScript Handler",
+    capabilities: ["javascript", "typescript"],
+  });
+```
+
+### Fallback Configuration
+
+If MCP tools are unavailable:
+
+```bash
+npx claude-flow hook pre-task --auto-spawn-agents
+```
+
+## Benefits
+
+- 🤖 Zero manual agent management
+- 🎯 Perfect agent selection
+- 📈 Dynamic scaling
+- 💾 Resource efficiency
