feat: Add orchestrator template and roles for executor and planner

- Created a new orchestrator template for Codex skill design, detailing structure and execution phases.
- Introduced the executor role with responsibilities for task execution, including routing to backends and handling implementation.
- Added the planner role for requirement breakdown, issue creation, and task dispatching, ensuring a structured planning process.

+# Agent Role Template
+
+Template for generating per-agent role definition files.
+
+## Purpose
+
+| Phase | Usage |
+|-------|-------|
+| Phase 0 | Read to understand agent role file structure |
+| Phase 3 | Apply with agent-specific content |
+
+---
+
+## Template
+
+```markdown
+---
+name: {{agent_name}}
+description: |
+  {{description}}
+color: {{color}}
+skill: {{parent_skill_name}}
+---
+
+# {{agent_display_name}}
+
+{{description_paragraph}}
+
+## Core Capabilities
+
+{{#each capabilities}}
+{{@index}}. **{{this.name}}**: {{this.description}}
+{{/each}}
+
+## Execution Process
+
+### Step 1: Context Loading
+
+**MANDATORY**: Execute these steps FIRST before any other action.
+
+1. Read this role definition file (already done if you're reading this)
+2. Read: `.workflow/project-tech.json` — understand project technology stack
+3. Read: `.workflow/project-guidelines.json` — understand project conventions
+4. Parse the TASK ASSIGNMENT from the spawn message for:
+   - **Goal**: What to achieve
+   - **Scope**: What's allowed and forbidden
+   - **Context**: Relevant background information
+   - **Deliverables**: Expected output format
+   - **Quality bar**: Success criteria
+
+### Step 2: {{primary_action_name}}
+
+{{primary_action_detail}}
+
+\`\`\`javascript
+// {{primary_action_description}}
+{{primary_action_code}}
+\`\`\`
+
+### Step 3: {{secondary_action_name}}
+
+{{secondary_action_detail}}
+
+\`\`\`javascript
+// {{secondary_action_description}}
+{{secondary_action_code}}
+\`\`\`
+
+### Step 4: Output Delivery
+
+Produce structured output following this EXACT template:
+
+\`\`\`text
+Summary:
+- One-sentence completion summary
+
+Findings:
+- Finding 1: [specific description with file:line references]
+- Finding 2: [specific description]
+
+Proposed changes:
+- File: [path/to/file]
+- Change: [specific modification description]
+- Risk: [low/medium/high] - [impact description]
+
+Tests:
+- Test cases: [list of needed test cases]
+- Commands: [test commands to verify]
+
+Open questions:
+1. [Question needing clarification, if any]
+2. [Question needing clarification, if any]
+\`\`\`
+
+**Important**: If there are open questions that block progress, prepend output with:
+\`\`\`
+CLARIFICATION_NEEDED:
+Q1: [question] | Options: [A, B, C] | Recommended: [A]
+Q2: [question] | Options: [A, B] | Recommended: [B]
+\`\`\`
+
+## Key Reminders
+
+**ALWAYS**:
+- Read role definition file as FIRST action (Step 1)
+- Follow structured output template EXACTLY
+- Stay within the assigned Scope boundaries
+- Include file:line references in Findings
+- Report open questions via CLARIFICATION_NEEDED format
+- Provide actionable, specific deliverables
+
+**NEVER**:
+- Modify files outside the assigned Scope
+- Skip context loading (Step 1)
+- Produce unstructured or free-form output
+- Make assumptions about unclear requirements (ask instead)
+- Exceed the defined Quality bar without explicit approval
+- Ignore the Goal/Scope/Deliverables from TASK ASSIGNMENT
+
+## Error Handling
+
+| Scenario | Action |
+|----------|--------|
+| Cannot access required file | Report in Open questions, continue with available data |
+| Task scope unclear | Output CLARIFICATION_NEEDED, provide best-effort findings |
+| Unexpected error | Report error details in Summary, include partial results |
+| Quality bar not achievable | Report gap in Summary, explain constraints |
+```

+
+## Template Variants by Responsibility Type
+
+### Exploration Agent
+
+**Step 2**: Codebase Discovery
+```javascript
+// Search for relevant code patterns
+const files = Glob("src/**/*.{ts,js,tsx,jsx}")
+const matches = Grep(targetPattern, files)
+// Trace call chains, identify entry points
+```
+
+**Step 3**: Pattern Analysis
+```javascript
+// Analyze discovered patterns
+// Cross-reference with project conventions
+// Identify similar implementations
+```
+
+### Implementation Agent
+
+**Step 2**: Code Implementation
+```javascript
+// Implement changes according to plan
+// Follow existing code patterns
+// Maintain backward compatibility
+```
+
+**Step 3**: Self-Validation
+```javascript
+// Run relevant tests
+// Check for syntax/type errors
+// Verify changes match acceptance criteria
+```
+
+### Analysis Agent
+
+**Step 2**: Multi-Dimensional Analysis
+```javascript
+// Analyze from assigned perspective (security/perf/quality/etc.)
+// Collect evidence with file:line references
+// Classify findings by severity
+```
+
+**Step 3**: Recommendation Generation
+```javascript
+// Propose fixes for each finding
+// Assess risk and effort
+// Prioritize by impact
+```
+
+### Testing Agent
+
+**Step 2**: Test Design
+```javascript
+// Identify test scenarios from requirements
+// Design test cases with expected results
+// Map to test frameworks
+```
+
+**Step 3**: Test Execution & Validation
+```javascript
+// Run tests
+// Collect pass/fail results
+// Iterate on failures
+```
