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.

+# Automatic Topology Selection
+
+## Purpose
+
+Automatically select the optimal swarm topology based on task complexity analysis.
+
+## How It Works
+
+### 1. Task Analysis
+
+The system analyzes your task description to determine:
+
+- Complexity level (simple/medium/complex)
+- Required agent types
+- Estimated duration
+- Resource requirements
+
+### 2. Topology Selection
+
+Based on analysis, it selects:
+
+- **Star**: For simple, centralized tasks
+- **Mesh**: For medium complexity with flexibility needs
+- **Hierarchical**: For complex tasks requiring structure
+- **Ring**: For sequential processing workflows
+
+### 3. Example Usage
+
+**Simple Task:**
+
+```
+Tool: mcp__claude-flow__task_orchestrate
+Parameters: {"task": "Fix typo in README.md"}
+Result: Automatically uses star topology with single agent
+```
+
+**Complex Task:**
+
+```
+Tool: mcp__claude-flow__task_orchestrate
+Parameters: {"task": "Refactor authentication system with JWT, add tests, update documentation"}
+Result: Automatically uses hierarchical topology with architect, coder, and tester agents
+```
+
+## Benefits
+
+- 🎯 Optimal performance for each task type
+- 🤖 Automatic agent assignment
+- ⚡ Reduced setup time
+- 📊 Better resource utilization
+
+## Hook Configuration
+
+The pre-task hook automatically handles topology selection:
+
+```json
+{
+  "command": "npx claude-flow hook pre-task --optimize-topology"
+}
+```
+
+## Direct Optimization
+
+```
+Tool: mcp__claude-flow__topology_optimize
+Parameters: {"swarmId": "current"}
+```
+
+## CLI Usage
+
+```bash
+# Auto-optimize topology via CLI
+npx claude-flow optimize topology
+```
