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.

+# Self-Healing Workflows
+
+## Purpose
+
+Automatically detect and recover from errors without interrupting your flow.
+
+## Self-Healing Features
+
+### 1. Error Detection
+
+Monitors for:
+
+- Failed commands
+- Syntax errors
+- Missing dependencies
+- Broken tests
+
+### 2. Automatic Recovery
+
+**Missing Dependencies:**
+
+```
+Error: Cannot find module 'express'
+→ Automatically runs: npm install express
+→ Retries original command
+```
+
+**Syntax Errors:**
+
+```
+Error: Unexpected token
+→ Analyzes error location
+→ Suggests fix through analyzer agent
+→ Applies fix with confirmation
+```
+
+**Test Failures:**
+
+```
+Test failed: "user authentication"
+→ Spawns debugger agent
+→ Analyzes failure cause
+→ Implements fix
+→ Re-runs tests
+```
+
+### 3. Learning from Failures
+
+Each recovery improves future prevention:
+
+- Patterns saved to knowledge base
+- Similar errors prevented proactively
+- Recovery strategies optimized
+
+**Pattern Storage:**
+
+```javascript
+// Store error patterns
+mcp__claude -
+  flow__memory_usage({
+    action: "store",
+    key: "error-pattern-" + Date.now(),
+    value: JSON.stringify(errorData),
+    namespace: "error-patterns",
+    ttl: 2592000, // 30 days
+  });
+
+// Analyze patterns
+mcp__claude -
+  flow__neural_patterns({
+    action: "analyze",
+    operation: "error-recovery",
+    outcome: "success",
+  });
+```
+
+## Self-Healing Integration
+
+### MCP Tool Coordination
+
+```javascript
+// Initialize self-healing swarm
+mcp__claude -
+  flow__swarm_init({
+    topology: "star",
+    maxAgents: 4,
+    strategy: "adaptive",
+  });
+
+// Spawn recovery agents
+mcp__claude -
+  flow__agent_spawn({
+    type: "monitor",
+    name: "Error Monitor",
+    capabilities: ["error-detection", "recovery"],
+  });
+
+// Orchestrate recovery
+mcp__claude -
+  flow__task_orchestrate({
+    task: "recover from error",
+    strategy: "sequential",
+    priority: "critical",
+  });
+```
+
+### Fallback Hook Configuration
+
+```json
+{
+  "PostToolUse": [
+    {
+      "matcher": "^Bash$",
+      "command": "npx claude-flow hook post-bash --exit-code '${tool.result.exitCode}' --auto-recover"
+    }
+  ]
+}
+```
+
+## Benefits
+
+- 🛡️ Resilient workflows
+- 🔄 Automatic recovery
+- 📚 Learns from errors
+- ⏱️ Saves debugging time
