Add missing repository components for complete supercharge.sh installation

Added all directories and files expected by supercharge.sh:

- hooks/ (5 hook scripts for session management and AI consultation)
- commands/ (3 custom slash commands: brainstorm, write-plan, execute-plan)
- plugins/ (plugin references for glm-plan, rust-analyzer, marketplaces)
- bin/ralphloop (Ralph Orchestrator wrapper for autonomous iteration)
- scripts/sync-agents.sh (agent synchronization script)
- templates/ (config templates: settings, hooks, config.json)

This completes the repository structure so supercharge.sh can install
all components without warnings.

+## Description
+
+Launches a collaborative brainstorming session using multiple AI perspectives:
+- Claude (primary)
+- Qwen (consultation)
+- Ralph Orchestrator (autonomous iteration)
+
+## Modes
+
+**Direct Mode** (simple tasks):
+- Quick ideation
+- Feature exploration
+- Design discussions
+
+**Ralph Mode** (complex tasks):
+- Architecture design
+- System planning
+- Multi-phase projects
+
+## Environment Variables
+
+```bash
+QWEN_CONSULT_MODE=always|delegate|off
+RALPH_AUTO=true|false
+QWEN_MAX_ITERATIONS=3
+```

+```
+/brainstorm "How should we structure the API?"
+/brainstorm "Design a notification system"
+/brainstorm "Plan the database schema"

+# /execute-plan
+
+Execute a previously created implementation plan.
+
+## Usage
+
+```
+/execute-plan
+/execute-plan my-plan.md
+/execute-plan --review
+```
+
+## Description
+
+Executes implementation plans created with `/write-plan`:
+- Reads plan from `.claude/plans/`
+- Executes each step in order
+- Creates checkpoints for rollback
+- Validates each step completion
+
+## Options
+
+```
+--review      # Review plan before executing
+--from=N      # Start from step N
+--to=N        # Execute through step N
+--dry-run     # Show what would be done
+--continue    # Continue after error
+```
+
+## Execution Process
+
+1. **Load Plan** - Read and parse plan file
+2. **Review** (optional) - Show steps and confirm
+3. **Execute** - Run each step sequentially
+4. **Validate** - Verify each step completed
+5. **Checkpoint** - Save progress after each step
+6. **Report** - Summary of changes
+
+## Examples
+
+```
+/execute-plan                    # Execute latest plan
+/execute-plan auth-plan.md       # Execute specific plan
+/execute-plan --review           # Review before executing
+/execute-plan --from=5           # Start from step 5
+```
+
+## Checkpoints
+
+Each step creates a checkpoint in `.claude/plans/<plan-name>.checkpoint/`
+Use `--continue` to resume from last checkpoint after failure.

+- Dependencies
+- Risks and mitigations
+
+## Plan Structure
+
+1. **Summary** - High-level overview
+2. **Technical Approach** - Architecture decisions
+3. **Implementation Steps** - Ordered task list
+4. **Files to Create/Modify** - Specific files
+5. **Testing Strategy** - Validation approach
+6. **Dependencies** - Required packages/changes
+7. **Risks & Mitigations** - Potential issues
+
+## Examples
