fix: improve workflow execute command and agent task parsing

- Fix bash command syntax in execute.md for Windows compatibility
  - Convert multi-line for loop to single-line format
  - Use single quotes for grep patterns to avoid escaping issues

- Simplify agent prompt template in execute.md
  - Path-based invocation instead of embedding task content
  - Add [FLOW_CONTROL] and "Implement" markers to trigger agent behavior

- Enhance code-developer.md Task JSON parsing
  - Add explicit Task JSON field mapping (requirements, acceptance, etc.)
  - Add STEP 1/2/3 execution flow for clarity
  - Add Pre-Analysis Execution format with command-to-tool mapping
  - Define default behavior when command field is missing
  - Priority: Use tech_stack from JSON before auto-detection

- Add execution_config alignment rules to action-planning-agent.md
  - Ensure meta.execution_config matches implementation_approach
  - "agent" mode: no command fields, cli_tool: null
  - "hybrid" mode: some command fields
  - "cli" mode: all steps have command fields

 ### Agent Prompt Template
-**Dynamic Generation**: Before agent invocation, read task JSON and extract key requirements.
+**Path-Based Invocation**: Pass paths and trigger markers, let agent parse task JSON autonomously.
 
 ```bash
 Task(subagent_type="{meta.agent}",
      run_in_background=false,
-     prompt="Execute task: {task.title}
+     prompt="Implement task {task.id}: {task.title}
 
-     {[FLOW_CONTROL]}
+     [FLOW_CONTROL]
 
-     **Task Objectives** (from task JSON):
-     {task.context.objective}
-
-     **Expected Deliverables** (from task JSON):
-     {task.context.deliverables}
-
-     **Quality Standards** (from task JSON):
-     {task.context.acceptance_criteria}
-
-     **MANDATORY FIRST STEPS**:
-     1. Read complete task JSON: {session.task_json_path}
-     2. Load context package: {session.context_package_path}
-
-
-     **Session Paths**:
-     - Workflow Dir: {session.workflow_dir}
-     - TODO List: {session.todo_list_path}
-     - Summaries Dir: {session.summaries_dir}
+     **Input**:
+     - Task JSON: {session.task_json_path}
      - Context Package: {session.context_package_path}
 
-     **Success Criteria**: Complete all objectives, meet all quality standards, deliver all outputs as specified above.",
-     description="Executing: {task.title}")
+     **Output Location**:
+     - Workflow: {session.workflow_dir}
+     - TODO List: {session.todo_list_path}
+     - Summaries: {session.summaries_dir}
+
+     **Execution**: Read task JSON → Parse flow_control → Execute implementation_approach → Update TODO_LIST.md → Generate summary",
+     description="Implement: {task.id}")
 ```
 
+**Key Markers**:
+- `Implement` keyword: Triggers tech stack detection and guidelines loading
+- `[FLOW_CONTROL]`: Triggers flow_control.pre_analysis execution
+
+**Why Path-Based**: Agent (code-developer.md) autonomously:
+- Reads and parses task JSON (requirements, acceptance, flow_control)
+- Loads tech stack guidelines based on detected language
+- Executes pre_analysis steps and implementation_approach
+- Generates structured summary with integration points
+
+Embedding task content in prompt creates duplication and conflicts with agent's parsing logic.
