refactor: Reorganize Gemini commands - move bug-fix to pre/bug-index

- Move bug-fix.md from gemini/chat/ to gemini/pre/bug-index.md
- Update command name from bug-fix to bug-index
- Update all command references to use /gemini:pre:bug-index path
- Delete obsolete chat/plan.md file
- Maintain template functionality while improving command organization

+### 📋 **Command Overview: `/gemini:chat:plan`**
+
+-   **Type**: Template-based Gemini CLI Wrapper
+-   **Purpose**: Comprehensive project planning and architecture analysis using expert planning template
+-   **Template**: Planning analysis template for systematic feature and system design
+-   **Core Tool**: `Bash(gemini:*)` - Executes Gemini CLI with planning template
+
+### 📥 **Parameters & Usage**
+
+-   **`<planning topic>` (Required)**: Description of the feature, system, or architectural challenge to plan
+-   **`--all-files` (Optional)**: Includes entire codebase for comprehensive planning context
+-   **`--save-session` (Optional)**: Saves the planning analysis to current workflow session
+
+### 🔄 **Execution Workflow**
+
+`Parse Planning Topic` **->** `Load Planning Template` **->** `Assemble Context` **->** `Execute Gemini CLI` **->** `(Optional) Save Session`
+
+### 📋 **Planning Analysis Focus**
+
+The planning template provides structured analysis covering:
+- **Requirements Analysis**: Understanding functional and non-functional requirements
+- **Architecture Design**: System structure, components, and interactions
+- **Implementation Strategy**: Step-by-step development approach
+- **Risk Assessment**: Identifying potential challenges and mitigation strategies
+- **Resource Planning**: Time, effort, and technology requirements
+
+### 📚 **Context Assembly**
+
+Context includes:
+1. **Planning Template**: @~/.claude/prompt-templates/plan.md
+2. **Project Guidelines**: @{CLAUDE.md,**/*CLAUDE.md}
+3. **Relevant Files**: User-specified files or all files if `--all-files` used
+
+### 📝 **Prompt Structure**
+
+```
+=== SYSTEM PROMPT ===
+@~/.claude/prompt-templates/plan.md
+
+=== CONTEXT ===
+@{CLAUDE.md,**/*CLAUDE.md}
+@{target_files}
+
+=== USER INPUT ===
+[Planning topic and any specific requirements or constraints]
+```
+
+### ⚙️ **Implementation**
+
+```pseudo
+FUNCTION execute_planning_analysis(planning_topic, flags):
+  // Load planning template
+  template = load_file(@~/.claude/prompt-templates/plan.md)
+  
+  // Construct prompt with template
+  prompt = "=== SYSTEM PROMPT ===\n" + template + "\n\n"
+  prompt += "=== CONTEXT ===\n"
+  prompt += "@{CLAUDE.md,**/*CLAUDE.md}\n"
+  
+  // Execute with appropriate context
+  IF flags contain "--all-files":
+    result = execute_tool("Bash(gemini:*)", "--all-files", "-p", prompt + planning_topic)
+  ELSE:
+    prompt += "\n=== USER INPUT ===\n" + planning_topic
+    result = execute_tool("Bash(gemini:*)", "-p", prompt)
+  
+  // Save session if requested
+  IF flags contain "--save-session":
+    save_planning_session(planning_topic, result)
+  
+  RETURN result
+END FUNCTION
+```
+
+### 💾 **Session Integration**
+
+When `--save-session` is used:
+- Saves to `.workflow/WFS-[topic]/.chat/` directory
+- File named: `plan-YYYYMMDD-HHMMSS.md`
+- Includes template used, planning topic, analysis, and implementation roadmap
+
+**Session Template:**
+```markdown
+# Planning Analysis: [Timestamp]
+
+## Planning Topic
+[Original planning topic description]
+
+## Template Used
+plan.md - Expert planning and architecture analysis template
+
+## Analysis Results
+[Complete Gemini response with requirements, architecture, and implementation plan]
+
+## Implementation Roadmap
+- [Phase 1: Foundation work]
+- [Phase 2: Core implementation]
+- [Phase 3: Integration and testing]
+
+## Key Decisions
+- [Architecture choices]
+- [Technology selections]
+- [Risk mitigation strategies]
+```
